LGTM

I would add some general notes in some places stating

1. For PR writer to tag maintainers with questions even once they have pushed and to use draft PRs when things are not ready yet. (We can also discuss in the issue if requried)
2. For PR reviewer - to tag maintainers when they have questions

I think you are missing to introduce the new md file in the TOC for mkdocs (you need tp modify the mkdocs.yml)

need to review again after last changes
