Re: Cross Site Cooking

We are investigating ways to improve on this method, but as far as I can
tell, any improvement will require a coordinated effort by all the gTLD
and ccTLD registries.

Any improvement will require that browsers only pass cookies to
domains which are explicitly permitted by the setter, and pass the
setter domain to all recipients alongside the cookie. IOW, a protocol
change. Anything else is papering over the cracks.

What about using DNS records, either a new kind, or something TXT-based (like SPF). Maybe we could have it so that the domain owner could make an allow cookies record, with a list of matching domains, and if it doesn't exist, then the browser will only allow the cookie to be set for the full domain, not a subset of it.
