On Ben's (2): "The only things that were removed that I wanted to check if we should think about keeping was the note that the same key might be referred to by different key IDs in messages directed to different recipients.  What do people think about that?"  I'm fine restoring that text.

Could you also do that, Ludwig?

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.")
