My list:

Tap location for contextual menus. A lot of apps need to know exactly where a context menu is being triggered from (e.g. canvas style editors etc).
Modifier key observation during button presses/gestures etc.
Cursor support
Native Undo Manager support (SwiftUI has Environment.undoManager but it just exposes Cocoa's UndoManager which doesn't feel very SwiftUI like).
Expanded File Dialog options (e.g. adding buttons to the dialog).
The outline variant of List (List(… children: …)) is missing a lot of the flexibility of NSOutlineView (TODO: flesh this out with concrete example).
