There's been some prototyping [1], though no serious code. +If this did happen, you'd be able to sync Gmail labels with notmuch +tags without any help from OfflineIMAP (OfflineIMAP could perform +better and use less disk space if it knew how to set up hard links +when talking to Gmail, but this would be entirely independent of +notmuch). You might also be able to work out cross-device sync, using +IMAP folder synchronization as a channel for tag synchronization. + +As for storing this information directly in messages, in general, the +notmuch community is opposed to modifying messages. This causes many +problems, and immutable messages are more robust and simplify so many +things. IMAP assumes messages are immutable. Maildir assumes +messages are immutable. Notmuch new would get dramatically slower if +it had to check for messages modifications. What do you do if you +change a tag and there are multiple copies of a message? What do you +do if there are multiple copies and they disagree about the tags? How +do you atomically update the tags stored in a message? From an +engineering standpoint, it's much better to avoid mutable messages. + +[1] id:874nk8v9zw.fsf@zancas.localnet
