At least in some setups (a lot actually) you would not need to
poll: GUIs could definitely trigger it.

I'm pretty sure there are IMAP servers with custom hooks (Dovecot?).
Not exactly easy but doable.

BTW: Does pollmailboxes _disable_ the event based notifications?
UPGRADE.txt is not clear about that.

Some setups might want to use a mix. Event-based with custom
triggers and polling-based with pollfreq=3600 as a safety net.
