While I believe that the responsibility for the mechanism that combines mac, crypt and pad should move from TLS to the cipher suites in the longer term, this extension seems to give most of the benefits without needing to port any cipher suites to AEAD

The document could be a little clearer if it used the same terminology as used in [TLS] such as "+" for concatenation and if it was more explict about the MAC e.g.

MAC(MAC_write_key, seq_num +
   TLSCompressed.type +
   TLSCompressed.version +
   TLSCompressed.length +
   ENC(TLSCompressed.fragment + padding + padding_length));

   where "+" denotes concatenation.
