Beginning with those very dangerous 3 words, *in my experience,* if folks
are doing something "different" in one place, they're also likely to be
doing something different in other places.  I've chased down enough build
errors reported by others that turned out to be caused by being different
in ways that would never succeed that I no longer think it productive of
my time to do so.  Others may of course feel different.

Unfortunately, as a project we don't seem to have enough spare bandwidth to
support those that wish to furrow their own path.  Until someone steps up
to fix the build process to work in all possible configurations on all
possible supported platforms, following the "established" pattern seems to
get folks to a productive state sooner.
