But there are places where cracking has a much higher up-front cost, or
a higher risk. So I don't argue that this recipe is right for all.
I'd argue that your approach is limited to fairly small sites.
that is, a large site (I'm mainly thinking of number and diversity
of users) needs to be hard

It's fine, especially right after it is released. It is supported for
