The title seems wrong, at least based on a quick glance this doesn't look like a UDP replacement. It could be a TCP replacement that's encapsulated in UDP.
There would potentially be huge benefits to be had from replacing TCP, but of course that's something the people have been trying to do for a long time and failed. Google has a huge advantage in achieving this thanks to controlling a significant proportion of clients and servers.
