I suspect that powertop is enough of a developer thing that if that's
the only thing that breaks, we don't have to worry too much.

I don't want to break *everybody*, so new distro's should be
up-to-date. But breaking something like a F14-15 timeframe distro or
something staid like a SLES (or "Debian Stale" or whatever they call
that thing that only takes crazy-old binaries)? It's fine. We don't
want to *rush* into it, but no, if those distros are basically not
updating, we can't care about them forever for something like
powertop.

Things that break *normal* applications are different. There the rule
really must be "never".
