So, in CoAP over TCP there is no issue since the connection terminology refers to TCP.
Hence, there is the question why the issues of renegotiation / post handshake authentication matter in DTLS when they do not matter in TLS.

3.3:

   Responses MUST be returned over the same connection as

So CoAP over byte-stream is clearly scoped to the connection.
