Err I meant the entire point of this to be that we can do nice things incrementally. E.g. I am linking LWN articles and whatnot to demonstrate that actually kernel devs thought some of this stuff is feasible. If anything, the heavy lift here is not even changing kernels, but reforming programming language's standard/popular libraries to make this stuff accessible and ergonomic --- most software today isn't written in C directly using some kernel-developer-maintained headers. If we can relatively make the OS changes, but it takes a bunch more slow steps for the new interfaces to percolate out "regular" developers, that adds uncertainty. "Latency" is a bigger enemy than "feasibility". You can find me jabbering away in many corners of the internet about trying to make standard libraries easier to evolve for precisely this reason. I want to keep evolving things, I am a big believe in https://www.joelonsoftware.com/2000/04/06/things-you-should-never-do-part-i/ https://www.joelonsoftware.com/2000/04/06/things-you-should-..., I just want things to evolve with a bit more foresight than the genetic algorithm can do on its own.
