Fairly recently `OPTYPE_DEPENDS_ON_CURSOR` was added, which makes the modal callback used to allow clicking on a face set unnecessary. There is no more instructional text in the status bar, but the changed mouse cursor should make that clear anyway. Removing the modal callback makes the behavior more standard, and avoids hardcoding the operator's keymap. Pull Request: https://projects.blender.org/blender/blender/pulls/109608
