If the github workflow for building documentation is changed to sphinx-build -W -n docs/ docs-build (add -n), then the nag message would have said that there was an issue. Otherwise, sphinx-build wasn't making any kind of warning/etc.

I changed it locally on my system, but it still complains, even when it seems correct. Unsure...
