I'm making some progress, I think I've changed the qa-frontpage in this
way, but unfortunately tex-team branched off master at a revision that
data.qa.guix.gnu.org hasn't got around to processing yet, so currently
there's no comparison.

Maybe the branch could be rebased or master could be merged in? If you
pick the latest commit with a green tick by it from [1], then that
should mean the data service is able to perform the comparison.
