LGTM. Would anyone else like to review?

[Kevin Buzzard]

I did 2/3 of a review, but am reluctant to sign off on the meta code and CI stuff because I don't know enough about these areas. I left a comment in the PR saying exactly which parts of the PR I had not reviewed.

Great, thanks! I've merged now.
