What are the examples of issues that have a dependency on PNE? This is a transform that is applied post constructing the packet and then before decryption on receive, so I was assuming its very decoupled from the core protocol and could be added at the end. If any part of the protocol adds a dependency on PNE, then it’s a cause for concern because it precludes the no-op transform for datacenter option. So stating any such dependencies is important IMO.

Yes.  There are a considerable number of issues backing up behind this now.
