That's enough to "remove" the email from the synced maildir and it's
going to be deleted on the remote on next sync.

No. However, this might help to read the emails and select/clean them.

Tip: a maildir is just a directory having the "cur", "tmp" and "new"
sub-directories. You could create a maildir called "archive-off" and
filter it from the sync process ('folderfilter' configuration option).
Emails _moved_ (with mv or an email reader) into this maildir would
stand in the local side only and deleted form the INBOX.
