Probably because the Triple Handshakes Considered Harmful paper from
earlier this year showed that using only the final message for channel
binding was broken and vulnerable, so there are IETF drafts for fixes to
TLS to provide something which actually offers a non-forgeable identity
for channel binding but nothing concrete yet (when I last checked, which
was a little while back now).
