Microsoft also has a separate API for 0RTT data.  I would characterize things as the two most popular browsers have stated their intention to have a single API, and the two most popular system libraries have two.  Outlier is clearly wrong.

I agree we don’t have consensus, but do make sure that any wording change accommodates the fact that the split isn’t all-versus-one.
