Thanks for writing this up! 
Specific to this text (see additional discussion on the issue): 

I don't think that we need any requirement about the distance between RetirePriorTo/SequenceNumber active_connection_id_limit. Setting a super high value would be a bit nonsensical, so some non-normative text explaining why doing that is a complete waste of everyone's time would be good, but it doesn't actually break anything. Saying "hey this is silly, consider that limit when you set this" is probably good enough just to make implementors aware of the foot gun. 

To the point about handshake and preferred address CIDs, I think it would be nice to have some text just as a reminder along the lines of "don't forget these have sequence numbers too" to help folks avoid confusion.
