Although it’s understandable to describe “what operators do”, the IETF isn’t a news service. We typically summarize these behaviors to take a position on them.

The draft provides a good description of the tradeoff between the privacy rights of endpoints and the rights of operators and the impact of both on protocol design on that tradeoff.

What I seem to be seeing is increasing “rough consensus” that the summary position should be closer to endpoint privacy than in the current form.

Although I don’t feel strongly that the text absolutely needs revision in that direction, I would oppose changes to relax or shift in the other direct.

They just strongly believe in their ideas. They will keep proposing the same idea over and over again (for years) till it gets published as an RFC..

That is, at least, in its original form, before this WG decided it needed to incorporate pro-encryption advocacy, greatly complicating the document and the resulting analysis.

I would be happy to help express those in a follow-on document. But this document describing where those conflicts lie is a *prerequisite* to developing those alternatives. And frankly those opinions are irrelevant to the intended content of *this* document.
