Green threads and async/await are orthogonal concepts. Both can be used at the same time and separately. Jep 425 brigns VM threads, but the API remains same as the old one. Without deep language extensions any concurrency improvements, in terms of usage, aren't possible. C#, Rust, JS made the successful leap, and imo Go route is very interesting.
