IMHO the better phrasing would be that it's the same concept that already existed for a long time, just formalized as part of a type system. Kind of similar to how we used to annotate types as part of a docstring, but type annotation syntax formalized that.

I'd say it's "correct" if you consider Iterable, Sizable, etc. as types - not in the sense of "a class" but in the sense of "can be used as a type annotation in place of a class-based type".

The overload the author sees might then be between protocol as an informal term, and as a typing feature.

I don't think @xeiaso.net is to blame here FWIW (they created Anubis), from what I can gather Gnome hard-coded a block role based on some User-Agent regex shenanigans. As usual it can easily be circumvented by pretending to be a newer Chromium. Sigh.

The Chromium projects themselves will remain under current, existing governance structures while just the new "Supporters of Chromium-Based Browsers" will be housed under the Linux Foundation.

(quotes added by me)

"Supporters of Chromium-Based Browsers" is the name of the initiative...
