> The internet transport ecosystem has been ossified for decades now, and QUIC breaks out of this ossification

But it's still just a layer on top of UDP, and still implemented at the application, like in the past. So how is the ossification broken?

Every app has to implement it itself rather than calling a syscall and letting the OS deal with its complexities (same as for TLS, making fewer apps implement it without a lot of extra work). Which also increases context switching. In the future more protocols will be built on top of QUIC, expanding the user-space stack, increasing fragmentation of application-space IP stacks. And are network cards now going to start implementing it?

It's painful to watch us stride headlong into the future depending on band-aids because surgery is too complicated.

No? I'll just link against one of the cross platform libraries that implements it, the same as for any other networking protocol. (Ex https://github.com/microsoft/msquic)

... do you not just link against a relevant networking library at this point? If not, why?!
