The problem combining move to trash with lazy expunge is that messages are stored in the expunge namespace twice, first when it was deleted from the original folder and the second when is deleted from the trash.

Not right now. Maybe it could be automatically done when SPECIAL-USE is enabled and the deletion is from a \Trash mailbox.

doveadm purge shouldn't affect lazy expunge, but you can disable lazy_expunge by using something like doveadm -o mail_plugins=everything,except,lazy_expunge expunge ..
