Comment (by bjorsch):

 I was about to file a ticket about this problem related to
 `add_menu_page()` and `add_submenu_page()`, but turned up this one in my
 preliminary search.

 We're running into the same problem while using Phan for static analysis,
 and we'd appreciate if callable parameters that also accept an `empty()`
 value to indicate no-callback were to be updated to be `callable|null`.
