"Remove support" is the correct path forward. Simply state that it is the W3C's position that this is harmful to the web as a whole, and that ad measurement/targeting (and ideally advertising as a whole) needs to stop happening.

Don't bend over backwards trying to figure out how to fit something nobody wants into the platform. Deprecate it.
