1) It seemed a bit difficult to implement at first. Probably easier now.

2) Updating FTS indexes when user doesn't use them is a waste of CPU and space. Of course, this could be done in a similar way as caching. Update FTS for mailboxes where it's actually used.

3) Squat's updates would still be slow..
