I didn't receive any opposition to my proposal, so I've created two
github pull requests for discussion - one for dovecot and one for
pigeonhole:
https://github.com/dovecot/core/pull/4
https://github.com/dovecot/pigeonhole/pull/2

I've also attached the two patches for review here in case that is
preferred. Please keep me in CC as I'm not subscribed to the list.

Thanks!
