GWGSo, first someone proposes something. We are now tracking that with issues, however, those issues are not linked in the proposed addition part of the h-entry page, which we do in the Micropub extensions page.
GWGIt notes in the change control protocol that there should preferably be a link to a step by step user scenario, which I assume should now be in the GitHub issue. It notes demonstratable using an existing single site tool.
GWGThen, we get to draft properties, which seems to imply that they must be published and consumed, and citations of other sites. But stable is 3 implementations of same.
