I'm not sure where we're going here. There are many jurisdictions around
the world with many requirements. Some of them may be helped by DNT in some
cases, some may not be. DNT is not the only way to meet those requirements.
If we can make DNT work for these requirements without making DNT overly
complex/cumbersome to implement, then I think it's worth considering
specific proposals, but that's a case by case basis depending on what we're
being asked to take on. I don't find this abstract argument particularly
helpful to be honest. (And frankly I don't think anyone is expecting that
someone who ignores DNT would be helped by DNT, so I don't even know why
you're bringing that up. No one has claimed that here to my knowledge.)

If there's specific actionable things for us to consider, let's consider
them, but I feel like we're talking about progressively less actionable
things.

Bringing us back to the point, for a moment. Some people have expressed
that they may reject DNT from some user agents. I haven't heard anyone
claim that "Receiving a DNT:1 and rejecting that DNT:1 is functionally
equivalent to having received DNT:0 from the user." DNT is fundamentally an
agreement between two parties -- if the parties don't agree on the terms
(server agrees by affirmatively acknowledging the client's DNT request),
there is no agreement, and the issue is moot. If you have regulatory
requirements to satisfy, you still have to satisfy them, without the help
of DNT.
