Please note, that all checks have passed (see here).
There seems to be a display bug, for me there's a message saying "Some checks haven't completed".

Fantastic. Lets pop open an issue to track resetting the GH Actions used here to the canonical ones as soon as they have supported releases (so noting what PR or whatever it is we have to hold out for).

The checks not completed messages is because I have some checks marked as required, but GHA only shows actions that have run on the target branch as options. This PR changes the CI matrix and the jobs that ran here in the PR are not the same ones as I have marked it to expect. I can merge with admin privs, then after these jobs run on master I'll be able to update the required CI jobs list for future PRs.
