It's interesting that a lot of the arguments against UDP are because networks deprioritize the packets or that routers don't handle them. If you know a message is going to be lost if you don't handle it, perhaps it should receive better or at least equal priority. Since TCP is chattier, anything that encourages people to use a lighter weight protocol would then benefit everyone, since there would be more advantages to using the less resource-intensive option. It's an interesting conundrum.
