[Dovecot] Feature request?

I'd like to toss a feature request on the table for consideration. We currently use a different popd because of a feature that allows us to restrict pop access based upon an allowed users list. This is the only thing that keeps us from using the popd in dovecot currently. It's a simple text file of usernames that are allowed to use pop, if the name isn't in that list then pop access is denied. Is this something that can be considered for a future feature addition? Would anyone else also find this useful?
