I suspect that QUIC would address some of these issues, however I also get the feeling that QUIC is just a reimplementation of TCP/IP in user land. Sure QUIC has some nice features that TCP/IP either doesn't have or implements poorly; priority, server initiated stream push. But others like different streams have different packet loss recovery (this is done in TCP normally, or UDP when packet loss isn't critical) is already achieved with the layer 3 / layer 4 split. The one benefit I can see with QUIC is that because it is a user level protocol it is more likely to be updated. Many embedded or IoT devices never get kernel updates, although they sometimes get user level software updates.
