I'd rather see us get a proper solver that would mean this should
never happen :-)

Yep, I am working on that. This is more of a short-term thing that I'm thinking of, just in case the proper solver isn't ready in time for pip 10. :)

Aside, I've just posted an update over at #988 -- https://github.com/pypa/pip/issues/988#issuecomment-360846457 -- about the state of the resolver work and the aforementioned branch.
