IDLE is supported while not fully stable. Syncing local changes
(Maildir) via inotify/fanotify/other is not supported.

This is what offlineimap does by default once a sync for a folder is
triggered. Concurrency is achieved by using more than one connection.

Not supported.

In IDLE mode, hooks are started for each new sync.

Supported.

No. Offlineimap has been always considered a syncer. However, it's
possible to get this done by using a script outside of offlineimap. The
script has to move the new emails from the remote out of the maildir
handled by offlineimap.
