symbol-or-music? would likely work as well. You just can't write
something like Staff.Script then.

Possibly. Pretty much all of the symbol-list-or-music? signature
functions return either an override (which is a music expression) or a
tweaked music expression (which obviously also is a music expression).
So there is no conflict of return type. But returning a void music
expression should also be fine.
