I know, but heres my bigger plan. I'm purposely creating many small examples that can be used for the data umbrella sprint. So this for instance is a fairly easy contribution for a newcomer to make, especially now that there's a single example.

This issue I created is another example of one thats suitable for a sprint. You very likely are going to see me merge other PRs like this in prep for the sprint.
#5326

If these are not completed for the sprint they still are good beginner examples to build community engagement in the codebase

Assuming the CI failure is a flaky one and merging
