This feedback isn't directed at any one person but that proposal impressively suffers from the simultaneous problems of Being Way Too Fucking Complicated and Proposing to Make the Web Better but Actually Making it Way Worse (for Everyone Except Entrenched Megacorps). It's the exact same problem that Google's "anonymous ad attribution" attestation swarms suffered, and luckily that never came to pass.

From looking at the pictures in that article, it seems like in order for me to be able to browse "protected" sites (aka, most of the corporate-owned web, once they are aware that this exists and turn it on because "bots bad") my browser is going to have to negotiate for some scant amount of "allowed access" tokens or other such thing, through some complicated protocol that halts any chance of us realizing a future for the web that looks any much different from "locked down approved browsers visiting approved sites in an approved way."

The further we allow the Web to stray from cURL http://example.com Just Working, the worse off we all are. So to reiterate, this proposal looks insane and not at all aligned with Mozilla's mission...
