dovecot - Feb 2021 - doveadm import uninterruptable?

I'm using

% doveadm import -u restore at backup.invalid mdbox:/home/archive/mdbox
"" mailbox INBOX header From $PATTERN

sometimes, I mistype the pattern and immediately try to stop the
doveadm command with CTRL-C - and this never succeeds.

Is it inentional that I cannot interrupt the "doveadm import" command?

Using 2.3.13 here.

This has been in TODO for years, but we've never gotten around to
implementing it. Not specifically doveadm import, but anything that is
processing multiple mails should be able to stop on a signal
(mailbox_search_next() would return error).

For now you can use ctrl-z and kill -9 %1
