because we don't want to implement --[no-]compaction-heuristic
as a command line switch to git-add?
Fine with me.

Stepping back and looking how the compaction heuristic turned out,
I think this is what we did not want to see, i.e. the need to bring it in
every command, but rather enable and release it. But we backed off
of the default-on, and now people may ask for the  --no-compaction-heuristic
in interactive add eventually, when they run into a corner case.

For now:
