Thanks Sid.

No, effective script origin is wrong. That takes document.domain into
account, we most definitely do not want to do that for new features.
I'm not sure what you mean by target, is there an updated editor's
draft available?

Sure, but that can still be done as an enum. Just needs to consist of
"1" and "0" then. But it seems somewhat bad practice to compromise the
legibility of the API due to size concerns over the HTTP header.

The empty string is not a valid value. If there's only three valid
states, returning different types makes for a very cumbersome API. Did
you talk to any JS developers?

I guess this is not yet done in the editor's draft?

HTTP, at least in browsers, uses the same URL implementation as APIs
do. I guess I don't really care what you decide to call it now,
although it seems somewhat confusing with the other documents the W3C
publishes, but you'll be wrong long term.

That seems like a bad idea. We should not propagate the broken model
of cookies further. New APIs must be origin-bound.
