No problems, it's totally fine to recommend that since it saves
small amount of storage and will speed up expiry[1]
FWIW, the DB schema is in the create_state_tables() sub of
lib/PublicInbox/POP3D.pm and hopefully easily understandable
even to non-Perl hackers.
[1] of course, there's hardly any users, so I'm not sure it matters
