locate.updatedb in 9-current doesn't do that, by default.  Arguably
you want the setuid checks to do it, so that you're aware of setuid
executables that are buried in old snapshots -- particularly if you
keep old snapshots of /usr around after a security update.

I could see the logic in having find not descend into .zfs directories
by default (if done in a sufficiently general way), although then
you'd have to introduce a new flag "yes, really, look at everything!"
for cases when that's not desirable.
