Yes. See the list from Pavel. And I wouldn't push for it otherwise.
There are some questionable asserts with an overhead which is not
directly visible but it just adds up. This is different that it is one
time boot rare thing.

Anyway, I guess I have put all my arguments on the table. I will leave
the decision to you guys. If there is a strong concensus about a config
option, then I can live with that and will enable it.
