Isn't the final point here that we are trying to let the user do the
dumbest, easiest thing? Maybe no Linux distribution
does this, but we are trying to cope with bad input from a user not using a
nice distro.

The price we would pay for cleaning up our internals is demanding that
users think more about the configure input. This
is not always a good tradeoff.
