I don't wanna advocate this sort of churn whenever we add extensions
that are implied by some other existing extension, and I certainly don't
want to /have/ to do it because there'll be dbts_check warnings otherwise.
New subsets being defined do not invalidate the old descriptions and
they should remain valid.

NAK for doing it to these 4 subdirs, even if the bindings are changed to
not warn about it anymore.

These go to other trees, so up to their maintainers what they want :)
