Review checklist

The author performs the actions on the checklist. The reviewer evaluates the work and checks the boxes as they are completed.

• Summary. Write a summary of the changes. Explain what you did to fix the issue, and why you did it. Present the changes in a logical order. Instead of writing a summary in the pull request, you may push a clean Git history.
• Documentation. Write documentation for new functions. Update documentation for functions that changed, or complete documentation where it is missing.
• Tests. Write unit tests for every change. Write the unit tests that were missing before the changes. Include any examples from the reported issue as integration tests.
• Clean up. The changes are already clean. Clean up anything near the changes that you noticed while working. This does not mean only spatially near the changes, but logically near: any code that interacts with the changes!

Thanks for starting this work!
I was looking into this on Friday but wanted to upgrade the K dependency first to integration-test things properly. This upgrade is still in progress at #3691

[jberthold]

I opened #3723 with your commit plus some (textual) adjustments on top of the changes required to upgrade K for the tests (the latter should be rebased out later)

Superseded by #3723
