Yes. EXPUNGE for every remove would be poor design for this reason.

I think that's a key point - IMAP protocol itself does not say anything
about trash folders, and the existence of any such thing on IMAP server
accounts is due to client applications. An initial implemention to the
protocol would, in my opinion, do well to just use the Trash Can metaphor
*per folder* as a way to present messages with \Delete flag set. (So
remove means apply remote \Delete flag & move locally to folder's trash.)
Other clients should be able to deal with \Delete flags, as it's clearly
the way it's done in IMAP.
