I get a feeling we should have a wiki, at least to allow for a community draft of the specs, before even attempting to push our suggestion to the official github repo (Since the core team is quite busy with implementing the current specification). Also it would allow non techy types to contribute directly in speccing.
This is to avoid duplicate suggestions, and to identify any clashes early. Plus a wiki is much faster to collaboratively edit than a github push, while ensuring that the community is on the same page in terms of their thoughts of what the next spec should be like.
In addition if we ever support extensions, it will need good help documentations (or even just normal syntax). This can help as well.
(Tried reddit wiki mode, but there is a size limit I think)
recommended to be at wiki.commonmark.org . And if possible, make it possible to sign in with a discourse account.
I see a good process as this:
Discuss --> community draft wiki --> draft push --> finalizing draft --> official spec
Unless, there is a better approach?
