I agree that is a goal, but I don't agree that it sorts ahead of sound
behavior.  And, that goal really should be addressed by something like
bacon@ has posted repeatedly, by someone who really cares about systems
with too-old compilers, rather than being held up as a reason to do
unsound things.

Also, I think we as a larger community have reached the point where
using gcc7 as a base compiler is no longer reasonable.  It's probably
only because of NetBSD's super-long release cycle (and LTS
distributions) that we are even having this discussion.  That to me
argues for not weighting "want to use a compiler that is too old to be
reliable" very much.
