As somebody directly involved in this space, that's a pretty bad summary. The spec for first party sets (not an RFC, just a draft) isn't in a great state. Google is going to implement it anyway, Microsoft is supporting, Apple basically said the spec was crap but they might be interested in a good version of it, and Firefox said they didn't like it.

Speaking as engineer.. the Firefox folks don't really get it. You can't just break what sites like StackOverflow and Wikipedia have been doing for years (and in some cases decades) and then say "you were doing the wrong thing." Some version of FPS will ship in browsers, probably in the next 2 years.

Quoting Apple's position directly "[...] Given these issues, I don’t think we’d implement the proposal in its current state. That said, we’re very interested in this area, and indeed, John Wilander [Safari lead] proposed a form of this idea before Mike West’s [Google] later re-proposal. If these issues were addressed in a satisfactory way, I think we’d be very interested. [...]"

Also it was a W3C TAG review. The W3C and IETF are different organizations.
