If you do wish to have the data tossed out for no good reason every so

really having trouble seeing how such behavior would be desirable enough

I don't quite follow you. The purpose of unlogged tables is for data
which is disposable in the event of downtime; the classic example is the
a user_session_status table. In the event of a restart, all user
sessions are going to be invalid anyway.
As was already mentioned, application logs. Unlogged tables would be
perfect for that, provided they don't go *poof* every now and then for
no good reason. Nobody's going to be too heart broken if a handful of
log records go missing, or get garbled, after a server crash or power
outage. Delete 'em all after every restart though, and that's a problem.
