when your MUA uses COPY, why/how should the server mangle it into MOVE? 
Should it forsee the later expunge? The server must reply to the COPY 
before it sees the later commands.
If you buy lemons and water, what would you think, if the shop gives you 
lemonade, because it (computer, roboter or shopkeeper) forsees that you 
want to put both together anyway?

The work around would be:
https://wiki2.dovecot.org/Quota/Configuration

search for Trash

The problem however is, that some MUAs use other mailboxes than "Trash".

"move to trash folder" is bad thing and painful, I agree with you.
Add the other aspect: Delete in another namespace.
