(Looking for input from Jan here as well.) I'd indeed prefer a more fine grained (justified per instance) approach like you suggest, but I wasn't really opposed to how it was done so far as it didn't seem like any of the BUG_ON()-s should actually be able to trigger, considering that there was no failure possible there till now.
