From the FAQ, QUIC is an experiment that they're building on top of UDP
to test out what a new layer 4 transport protocol built with modern http
in mind  ought to look like. They say that they eventually want to fold
the results back into TCP (if possible, but given their goals it doesn't seem
especially likely that the result would still be TCP).
