I was preparing to make a similar patch and happily found that @c-rhodes has just landed one with basically the same idea behind. However I noticed that one of the tests was not updated correctly, hence this tiny NFC patch.

Since I don't have commit access, please help me add reviewers and merge the PR if it looks good to you. Thanks!
