I think it'd be useful not to have all the changes in one lump, but
structure this as a patch series with related changes in separate
chunks. I doubt we'd like to mix the changes in a single commit, and it
makes the reviews and reasoning easier. So those NULL-handling fixes
should be in one patch, the MCV patches in another one.
