Currently the expire database is used to only filter out users who don't
have anything to expunge. Some day in future it will filter out also
mailboxes that don't have anything. So if your total number of mailboxes
isn't very high, it's not very helpful.
But, now that you mentioned it, doing a "savedbefore 7d" search would go
through all the messages from the beginning of the mailbox rather than
from the end or doing a binary search. Maybe that should be optimized..
