That could be a silent breaking change to potentially a lot of users; I
would be against that.  Export notwithstanding, we don't just pull things
out of the standard.

If someone were to propose making it deprecated in C++17, I could be for
that.

Because this is a breaking change, I would like to see such a proposal talk
about the practical use cases for having a vector<bool> that was just
another instance of vector.  What are the useful things that cannot be done
/ cannot be done efficiently now with vector<bool>.
