I'm in the process of doing the PR, but I noticed that I can only 
address Ben's (1) and (3).

For (2) Ben was asking for our opinion.

I think we could take the note about different key IDs referring to the 
same key and reintroduce it in the text as it is a useful reminder.

(I mean that chunk:
" Note that the value of a Key ID is not always the same for different 
parties. When sending a COSE encrypted message with a shared key,
the Key ID may be different on both sides of the conversation,
with the appropriate one being included in the message based on the 
recipient of the message.")
