@tsalo I think I resolved the merge conflict here, but it's unhappy with the 3.12 unit tests (probably because this PR was created before we updated to allowing 3.12). Any clue how to fix this? Is there a way to have the all-contributors bot generate a new PR and then just close this one?

[handwerkerd]

Syncing with Main and re-running tests resolved the previous CI failure

This is really minor and I assume I can merge with only one review. If @tsalo, @eurunuela, or someone else doesn't skim this and approve by Wednesday, I'll just merge.

LGTM!
