also true that there's no real reason for anything outside of the actual timer

Not agreed: how do I get reliable per-CPU load stats in userland without sysctl
kern.cp_times
that exports incrementing raw "stathz-tick" counters? I need them to draw
per-CPU graphs.
Hmm, I guess userland needs the resolution of the values in the sysctls, yes.
To be clear, I was not at all saying that cp_times should be removed, only that
very little code in the kernel needs to use the literal C symbol 'stathz'
compared
to the C symbol 'hz'.
