Some servers support an additional expunge command, uid expunge, where
you can expunge only specific selected messages.

The main issue is that we have a common api to all backends.  If we were
to add this api capability, we'd have to emulate it for those (majority
of) backends/servers that don't support it natively.  And for imap this
emulation isn't guaranteed to be correct, and is pretty messy to
implement (you have to undelete any deleted but uninteresting messages,
delete the ones you want to delete, then expunge all deleted messages,
then re-delete the others).
