Please elaborate. Why is it "good" to have a separate network stack element in each application, and what does this mean for legacy applications that will never support QUIC?
Because different applications have different needs and there is nothing intrinsically safer or better about having the stack be kernel-resident and, in fact, a lot to recommend moving things out of the kernel and into userland, which has a better application cotenancy model (full cr3 context switches between different users).
Circumventing the role of the operating system in the name of improved efficiency and duplicating a once-centralized function in (some) applications doesn't seem like a well thought out course of action. Why have an operating system at all? Why not just boot your computer to each application you want to run, as was done on the early PCs of the 1980's?
Perhaps we shouldn't use computers to run our applications anymore. Everything could run on a gaming console. That would certainly be more efficient for the applications.
