Someone might want to save sessions to the database if, for example,
her WordPress-powered site employs load balancing.

By the way, I wasn't suggesting that one use transients in particular
for session storage---just that saving sessions to the database seems
more like the "WordPress way," with transients as an example of that
"way."
