I actually would prefer that we just say "this is the default now" and
provide some knob "no-indent-heuristic" or "no-compaction-heuristic"
and go with that, I think, since I am pretty sure we're all in
agreement that the heuristic is an improvement in almost every case,
certainly all the ones we've found. It's at least not worse in any
case I've seen, and is usually better.

Thoughts? I don't have a super strong opinion about which name we went
with for the knob.

Thanks,
Jake
