> This shows how browser developers race to provide new features ignoring privacy impact.

I think it showed how many years ago browser vendors were naive with understanding how this tech could be misused.

These days I think browser vendors are very much aware of it and will frequently block features or proposals that they feel compromise on privacy and/or could be used as a tracking vector, especially Firefox and Safari. Sort this list https://mozilla.github.io/standards-positions/ by Mozilla Position to see the reason they reject/refuse to implement standards and proposals.
