I'm pretty sure no one is saying that a site should be non-compliant by failing to second-guess the user agent.  There is nothing in any of the drafts today that would render you non-compliant by honoring a DNT:1 header from a browser that set DNT:1 by default.

DNT was always intended to be a global solution.  I do not see the point in rewriting the standard to allow for third parties to state that they kind of follow DNT.  If some third party wants to try that outside of the standard, they can obviously do so, but we should not facilitate an outcome that runs contrary to the very purpose of DNT.

Question - if a site decides to honor any and all DNT:1 signals, regardless of whether the browser is non-compliant because it set DNT on by default, would the site be in non-compliance?
