Just some minor notes, otherwise this looks good to me. Thank you!

I'd also like to explicitly highlight the transition from "public room directory" to "published room directory" as being one the ecosystem will need to adapt to. And if you could just audit the diff to make sure we're using "published room directory" vs. "room directory" in all the right places.

I'm slightly unsure how exactly to reflect this in the spec text. Or did you just mean calling it out explicitly in the changelog?

Have changed the wording accordingly in all applicable places with 9f17ab0.
