It is only a 'three packet handshake' if you ignore the off path interactions with the DNS service. The timeout on DNS tens to be rather smaller than that most would be comfortable with for crypto.

I wrote a blog post about how something like DANE could be used instead
of certificates for the TLS handshake to get it back to the original 3
packet handshake. I know that isn't news to a lot of people, but the
interesting part is that a Google could perform an experiment to see how
well it works in real life just like they did with Quic and Spdy. Since
Quic is all about making setup time faster, it seems like a pretty
reasonable experiment since it would cut out 2 packets generally
speaking since DNS can be cached.
