It also turns out that our previous pull requests hadn't passed through CI properly due to an incorrect GitHub setting (mea culpa!). This PR does do something useful, and will also make sure we pass CI before a release!

Yep, I accidentally recreated the same changes you did (I should have checked first!). Ready for merging (I don't think that second commit should be squashed).
