+`IGNORE_MOD_TAP_INTERRUPT_PER_KEY` has been removed and `IGNORE_MOD_TAP_INTERRUPT` deprecated as a stepping stone towards making `IGNORE_MOD_TAP_INTERRUPT` the new default behavior for mod-taps in the future.
+
+In place of the now removed `IGNORE_MOD_TAP_INTERRUPT_PER_KEY`, one must use the pre-existing `HOLD_ON_OTHER_KEY_PRESS` option.
+
+In most cases, updating `get_ignore_mod_tap_interrupt` to `get_hold_on_other_key_press` is simply a matter of renaming the function and swapping every `true` by `false` and vice versa. The one subtlety you may need to look out for is that the `get_ignore_mod_tap_interrupt` was only ever called with mod-taps passed in as the `keycode` argument, while the `keycode` argument of `get_hold_on_other_key_press` can be any dual-role key. This includes not only mod-taps, but also layer-taps, one shot keys, `TT(layer)` and more. This has an impact on the effect of the `default` case in a typical per-key configuration making use of a `switch(keycode)` statement.
+
+To illustrate, let's take the example of a configuration where we'd want all mod-taps to activate the modifier if another key is pressed while held with the exception of `LCTL_T(KC_A)`, which should ignore keys pressed while it is held and activate the modifier only if it has been held for longer than the tapping term. In addition, we would like to keep the default "ignore-interrupt" behavior of layer taps.
+
+An old way to do this would be via the following code:
+
+```c
+bool get_ignore_mod_tap_interrupt(uint16_t keycode, keyrecord_t *record) {
+    switch(keycode) {
+        case LCTL_T(KC_A):
+            return true;
+        default:
+            return false;
+    }
+}
+```
+
+The correct way to update this code without accidentally changing how the layer-taps work would be the following:
+
+```c
+bool get_hold_on_other_key_press(uint16_t keycode, keyrecord_t *record) {
+    switch(keycode) {
+        // Capture all mod-tap keycodes.
+        case QK_MOD_TAP ... QK_MOD_TAP_MAX:
+            if (keycode == LCTL_T(KC_A)) {
+                // Disable HOLD_ON_OTHER_KEY_PRESS for LCTL_T(KC_A)
+                // aka enable IGNORE_MOD_TAP_INTERRUPT for LCTL_T(KC_A).
+                return false;
+            } else {
+                // Enable HOLD_ON_OTHER_KEY_PRESS for every other mod-tap keycode.
+                return true;
+            }
+        default:
+            return false;
+    }
+}
+```

The “permissive hold” mode, in addition to the default behavior, immediately selects the hold action when another key is tapped (pressed and then released) while the dual-role key is held down, even if this happens earlier than the tapping term.  If another key is just pressed, but then the dual-role key is released before that other key (and earlier than the tapping term), this mode will still select the tap action.

 Note that until the tap-or-hold decision completes (which happens when either the dual-role key is released, or the tapping term has expired, or the extra condition for the selected decision mode is satisfied), key events are delayed and not transmitted to the host immediately.  The default mode gives the most delay (if the dual-role key is held down, this mode always waits for the whole tapping term), and the other modes may give less delay when other keys are pressed, because the hold action may be selected earlier.
 
+### Comparison :id=comparison
+
+To better illustrate the tap-or-hold decision modes, let us compare the expected output of each decision mode in a handful of tapping scenarios involving a mod-tap key (`LSFT_T(KC_A)`) and a regular key (`KC_B`) with the `TAPPING_TERM` set to 200ms.
+
+By default, mod-taps behave like `HOLD_ON_OTHER_KEY_PRESS`, while layer-taps behave like "Ignore Interrupt" out of the box. If you want "Ignore Interrupt"-like behaviour for mod-taps, you must enable `IGNORE_MOD_TAP_INTERRUPT`, or return `false` in the `get_hold_on_other_key_press` function for all mod-taps.
+
+Note: "`kc` held" in the "Physical key event" column means that the key wasn't physically released yet at this point in time.

 Normally, if you do all this within the `TAPPING_TERM` (default: 200ms), this will be registered as `al` by the firmware and host system.  With the `HOLD_ON_OTHER_KEY_PRESS` option enabled, the Layer Tap key is considered as a layer switch if another key is pressed, and the above sequence would be registered as `KC_RGHT` (the mapping of `L` on layer 2).
 
-?> The `HOLD_ON_OTHER_KEY_PRESS` option also affects Mod Tap keys, but this may not be noticeable if you do not also enable the `IGNORE_MOD_TAP_INTERRUPT` option for those keys, because the default handler for Mod Tap keys also considers the “rolling press” sequence like shown above as a modifier hold, not the tap action.  If you do not enable `IGNORE_MOD_TAP_INTERRUPT`, the effect of `HOLD_ON_OTHER_KEY_PRESS` on Mod Tap keys would be limited to reducing the delay before the key events are made visible to the host.
+?> The `HOLD_ON_OTHER_KEY_PRESS` option is essentially redundant with the default mod-tap behaviour. The only notable difference is that `HOLD_ON_OTHER_KEY_PRESS` reduces the delay before the key events are made visible to the host.

 ## Quick Tap Term
 
 When the user holds a key after tapping it, the tapping function is repeated by default, rather than activating the hold function. This allows keeping the ability to auto-repeat the tapping function of a dual-role key. `QUICK_TAP_TERM` enables fine tuning of that ability. If set to `0`, it will remove the auto-repeat ability and activate the hold function instead.
