Summary: Has enough positions to pass.
I'd like to see the Gen-ART reviewer's comment addressed per the discussion on the list.
Like EKR I'm confused / concerned about what happens if 2 experiments choose the same codepoint -- while there isn't really anything that the document can really do to prevent it, I think that it is worth having a bit more text mentioning that implementors should consider this, and e.g experimental use should handle failures differently to production. Seeing as EKR is carrying the DISCUSS I'll ballot NoObj and follow along.
Thank you for addressing my discuss
