Then there's no reason not to document it.

  Warning: FORCE_ROOT_INSTALL can render your system unusable by
  overwriting existing configuration files.  Do not use it unless you
  are completely aware of the consequences.

And yes, a descriptive name like FORCE_ROOT_INSTALL, not
HISTORICAL_MAKE_WORLD.

FWIW, that's when the rot set in IMO.  One of the nice things about
FreeBSD *used* to be that to upgrade the system you just needed to do
"make world".  Now you have a lot more work.

The only justification for this regression is that it's really
difficult to get everything right.  But that's a bug, not a feature.
