It would be best to move them to a “doc” output, so that users can have
them handy and be sure it’s the documentation that correspond to the
version they’re using.

OK with this change.

That may call for a better system to override dependencies and build
options à la Spack.

OTOH, we do want common variants to be available explicitly as packages
so that they get built on Hydra and so on.

Food for thought...
