An upstream demanding -Werror should work means upstream would need to
test rather a lot more than their own favourite
distro/architecture/library versions/kernel/userland, which isn't
going to happen.

Upstream does not need to take into account warnings produced by
compilers for lesser known architectures, as explained above.
As an upstream development aid to check code that has just been added
or changed, -Werror is fine, but not in the wild jungle that is Gentoo.
You might as well just look at the warnings themselves instead of
breaking the build system by making them fatal. In other words, for
upstream development it's convenient, but never for our users out there.
Also, bug reports based on *FLAGS=-Werror will be closed as INVALID.
(Perhaps we should document that too.)
