I’d like to pickup this conversation again. TL;DR I think inline (interactive!) user guides implemented as help topics could be very valuable & really quite easy to implement in the short term. Trying to bring farmOS.org into the mix adds complexity and will prevent us from making progress here.
See my thoughts here: Consider leveraging help topics for module documentation [#3243901] | Drupal.org
And a tiny example of what this could look like here: Help page · Issue #1 · paul121/farm_regen_digital · GitHub
