This was cc'd to the DNT group (which I removed), but not the html-media group;  it seems that members of the owning group might like to know of this, so that they can help clarify aspects of the spec etc.

should we send a note?

public-html-media@w3.org <public-html-media@w3.org>

I don't fully understand those details myself, and have asked for more discussion that might shed some light on a privacy review, which I think would be a suitable discussion for the Privacy Interest Group. It could be relevant to the Tracking Preference Expression spec to the extent that we have discussed making the Do Not Track signal accessible to plugins or extensions.
