I don't agree that "dpkg-buildpackage sets additional environment variables
to implement a distro/site policy for builds" implies "calling debian/rules
directly is unsupported". Or maybe I've misunderstood, and there are Debian
developers who are building official packages for *upload* by calling
debian/rules by hand, and that's what people are concerned about preserving
while still getting the benefits of these distro build flags?
I hadn't considered that possibility, because I can't imagine anyone wanting
to build packages that way instead of using dpkg-buildpackage, which does it
all in a single command. So I really don't consider that an important use
case, weighed against the concerns I outlined.

Er, both debuild and pbuilder invoke dpkg-buildpackage. So it seems clear
to me that the only difference would be when calling debian/rules directly,
and at that point you're opting out of lots of other conveniences, not just
distro build policy.
