Actually, thinking about this further, I'm wrong on (at least) one point above:  Version negotiation adds an RTT to whatever TLS requires.  So if the client guesses incorrectly, 1-RTT handshakes will take 2 RTTs to complete, because the TLS ClientHello can't be delivered successfully until client and server agree on the format.

That means the first time worst case is 2 RTTs, and eliminating one of them is worthwhile.
