> Without using a "stream", you'd need to do book-keeping of the CID-sequence number relation being received by the NEW_CID frame, because the frames can arrive out-of-order. "Stream" guarantees in-order-delivery and therefore you only need to maintain a counter.

At least in my implementation, I'd have to write a separate implementation of that CID "stream", unless we reuse an actual QUIC stream, so as far as I can see, it wouldn't make a big difference.

> Not carrying NEW_CID and RETIRE_CID as a "message" on top of "streams" also means that you would have a retransmission logic specific to those frames.

Why is that? They'd just be normal retransmittable frames, wouldn't they?
