Thanks for taking this on!

My preference is to have separate documentation packages when this
allows us to avoid a host of intermediate bootstrapping packages.  This
was acceptable for numpy and matplotlib in the past, but now that the
cycle has grown even larger, I’d prefer to cut the dependency by turning
them into separate packages.
