The way I read it, this name says "a function which tells us if
delete-selection uses the region".

It's not about "the current command" but about self-insert-command
(which may be the current command or may be called by the current command).

An alternative would be to copy the `delete-selection' (and
`pending-delete') property of `self-insert-command'.  Probably in an
after-load, tho.
