That certainly is the way it looks, to summarise the draft says: " As seen, different transports use encryption to protect their header information to varying degrees. There is, however, a trend towards increased protection with newer transport protocols.

Our guidance on scoping means that we can include deployed methods, are there examples that you can tell us about? > In particular, I > still think possibility of using extension headers is far too easily > dismissed by the draft (please see my previous comments about that). I also think there may be potential here in future, and would love to see this area explored - it is a topic in which I have research, and I believe you also. I can't however point yet to deployment examples in this area. Do you know more?
