P.S.  I think that there's much traction to the idea of moving from
COMPAT_FREEBSDx to some other variable called, for example,
COMPAT_FREEBSD_BACK_TO=x, which will give compatibility for binaries
as old as FreeBSD x.0, and have all the other magic handled behind the
scenes.  This would render the inconsistency with COMPAT_FREEBSDx part
of the debate completely moot.
