If we operate under the premise that an enumeration of "top-level third
parties" is required for consent to be meaningful in the E.U. but not
globally, then I would argue that the preferred way to satisfy this is by
doing something where we shift the balance of where the "compliance text"
lives from the browser to the website. That is, somewhere, a user is going
to be offered text explaining why they are being asked for an exception,
what the exception covers, and what this means. I would argue that in the
context of the browser, we're working across too many jurisdictions to
actually say anything too meaningful about what the exception means. (We
also tend to shun long text in our UI).

What I would therefore propose is that for a site in the E.U. wishing to be
compliant with whatever regulations end up being relevant, is that it could
satisfy those regulations via text on the page that hosts the "grant an
exception button". That is, the site could say,

"Dear user,

In an effort to provide you with high quality content, we have determined
that we need to serve users targeted ads. These ads provide a higher amount
of revenue that is otherwise possible, and this revenue directly pays for
the content you are about to enjoy. We use the following third party
service providers on our website:
- A Inc.
- B GmbH.
- C S.A.

If you grant an exception to our website, the third parties on our website
will be able to track your visits on our website for the purpose of serving
you more targeted content, including more relevant ads that we hope will
create a more meaningful interaction with our website.

Our DNT policy, located at <X> (and presumably referenced via some well
known location and/or response header) also lists out the third parties
that may be in use at any given time.

Click <here> to grant an exception to third parties on example.com from
your Do Not Track preference."

This still leaves open the possibility of third parties changing over time,
but I will posit that it's a bit unclear if it's actually required to
re-confirm consent at this time if the user has already been told that
their data will be used by third parties for the following purposes and
there's a clear way for them to discover what those third parties are at
any given time. (If you really cared, the browser could compile a list of
first-level third parties as well, after the page is loaded.)
