We have a roadmap repo for the RFC process: https://github.com/withastro/roadmap
We often have pretty good minimal user docs in the Stage 3/proposal, but even Stage 1 to just propose something encourages adding "end-goal" code examples of what it could look like if you're updating/changing/creating an API.
As for writing about our docs workflow, we've mostly focused on our community contributor process & guides like Astro Docs Docs (AD²) https://contribute.docs.astro.build , but a great idea!
