I figured I’d take a minute to try and find the proposal itself, so I could see what the proponents considered the virtues of this to be.

I stopped reading after the explainer’s intro section. The first example is making it easier for websites to sell adds (lmao) and the other 3 are extremely questionable whether if the proposed remedy even helps. And it’s presented as a benevolent alternative to browser fingerprinting, as if we must choose between these two awful choices. It’s an absolute joke of a proposal.
