Surely, it would take some resistance to remove valarray<> and to
improve it ;-)

FWIW, I would vote for improvement than removal.

But Beman is right: if no one works on numerics in C++, there is no
much improvement, even with the best intention from those on the
committee.

Some of these topics have been proved by practice, some still
constitute active research fields; for the latter category, I would
recommand caution.
