Well, printk message formats are not an API. I agree, though, that if
this is how kernel testing is going to get told about crashes, then we'd
need some sort of parsing specification which gets changed together with
when the actual messages are changed, so that tools don't break.

Or something slicker and more robust than tools parsing dmesg output...
