As it turns out, my sample tox.ini provides a pretty good use case for
it, I think. I would miss it if it were removed.

I don't see the confusion around precedence either, I think the visual
"binding" implies strongly that in "foo-!bar-baz" the negation applies
only to "bar", so as long as that is the behavior I don't see a problem.
