I agree it would be useful to explain this, e.g., that the reason is that TLS/SSH doesn't protect the transport layer from interruption (even if such interruption is recoverable).

7.3 regarding MD5. At the very least, there should be a note that
TCP-MD5 has been obsoleted by TCP-AO.

Agreed. And that the reason for its use is support for legacy systems where TCP-AO is not yet available, as per the AO RFC.
