Great proposal.
When we at Wallfacer made our recent post,
[ARC] RWA Facilitator Onboarding Framework , we made it as an ARC because that felt like the most official first step, but at the same time, I was pretty unsure. “Temp check” feels more descriptive for what our post actually was.
Your proposal above seems like a great way to make the process clearer (and hopefully encourage more community involvement!)
