The recent WASI 0.2.0 submission/discussion is about WASI, a chiefly server-side oriented system & so far server-side component model, but this component model is the cross-platform gateway that is opening up the (vastly larger now) webdev world to something that a long time ago the web was incredibly at: being a place for many different languages to come & try stuff out. And this time it'll be in a cross-language form! https://news.ycombinator.com/item?id=39143054
You're right it's been a direction for a long time. I hope some other languages & communities can find & expose worthy incredibly interesting offerings that lure us off the beaten path we are on. It'll be technically/mechanically much easier to do, starting now-ish, but whether there is distinct clear value to writing your core in other languages is so far very unclear. Will it make a difference? Will other ideas arise & prove valuable & steer us onwards? T.B.D.
So this is about EU making cycles in American History? :)
