Right. Honestly, as a Revelation user with a ten character password, the
blog post honestly did not make me feel like 'oh shit I need to change
everything immediately'. I don't use Revelation because I consider it
likely that some determined attacker is going to acquire a copy of my
database file (in itself not trivial) and then throw several weeks of
high-end processing power at accessing my password database. I use it
because it's a very effective way of ensuring things like the LinkedIn
password database breach have a very limited impact on me.

I don't think the vulnerability is sufficiently serious to justify
effectively killing the package, if I'm understanding the description
