Scratch "in a different lifetime". Granted, we don't have the problems
of yore, we do have big, cheap disks and don't have to make do with /usr
mounted over NFS. Still, I like to have a small root volume with all the
essential, can't-live-without-them tools on it, simply because it's a so
much smaller target if disaster strikes -- it's good to have it at hand
to salvage what's salvageable in this case. I'd be very pissed if I
couldn't setup my systems this way just due to somebody's feelings about
prettiness being violated.

Tab completion is a real usability kicker for having sbin vs. bin: it
benefits tremendously from having only those commands in your PATH which
are sensible to be used. Everything else just clutters up your display
if you use TAB-TAB to find commands.
