I've seen it, I've just not cared deeply.
I suspect the main issue is if you can cause debug dumps as a normal
user and find kernel addresses that way, but I'm not sure how much we
care. Somebody _actively_ debugging things might need the address, and
KASRL etc be damned.
I also suspect that everybody has already accepted that KASLR isn't
really working locally anyway (due to all the hw leak models with
cache and TLB timing), so anybody who can look at kernel messages
already probably could figure most of those things out.
So as long as the dumping isn't doing something actively stupid, and
as long as hex dumping isn't something that is easily triggered, this
probably falls under "nobody cares".
