@djsumdog I think this got cut off, but labels as folders is brilliantly easy to discover, most people use them just like folders. It just works.
IMAP keywords meanwhile do not present a consistent workflow between clients, and are too dissimilar in workflow from Gmail in clients where they do exist.
So I agree with the model chosen by Gmail and Fastmail. It's technically nasty but it just works for most users, only a couple nerds go around downloading their emails over IMAP anyway
@robryk I don't know. I use lieer to sync to local Maildir with notmuch and don't do IMAP anymore.
But maybe? I guess it depends on the client. Notmuch for example dedupes by message-id, so reading one copy reads all of them. So if you sync locally, then import into notmuch you'd get good behaviour again.
@robryk talking about a streaming client (w caching) like thunderbird vs a local sync client like imapsync
