It should all be caught during testing either way. And if some OOT module
does something nasty, that's not our responsibility.

BUG_ON is not a way to write assertions into the code.
So you'd rather create exploits than crashing on a fundamental API
violation?  That's exactly what the series is trying to fix.
I'd rather have a sane API that doesn't even allow this level of 
flexibility with NOFAIL.

But probably I'm missing more details here why this all has to be so 
complicated ;)
