Yes, and so do many other clients. But FTS indexes are useful for
webmails, mobile clients and other clients that don't have a local
cache.

Squat indexes are going to work so that the first time you do a TEXT or
BODY search the indexes are built for the mailbox. After that they most
likely are updated when saving new mails (although maybe only with
deliver, not with APPEND/COPY?). If user hasn't done any TEXT/BODY
searches for a month or so, the indexes finally get deleted. Or that's
my plan currently, those rules are easy to change.
