if we're interested in coming to consensus, i'll pipe up and say i really like the idea of mtime being proc start time. i've wanted this many times and only didn't add it because i (foolishly) assumed it'd be more involved than the apparently-trivial diff. being able to 'ls -lt /proc' is genuinely useful, and i'm curious why you'd dismiss it. as you say, the compile time of the kernel is useful (and not really confusing) as well, but is preserved in nearly every other device on the system.
that said, i totally understand why #9fans discussions don't carry much weight in the rest of the world. ;-)
