One (mostly psychological, but still serious) problem is that stack dumps make panics always look like kernel bugs. But there are panics which are definitely not kernel bugs: like the popular cannot mount root or machine checks or a couple of others.
We do not want users to send all these panics to linux-kernel and they would if they look too much like kernel bugs.
I think it's in principle a good idea, but only if you distingush the cases which are not kernel bugs. e.g. use a different panic() call for them that does not dump.
