> Green threads/Virtual threads are one solution, but then you need to ship a runtime for them, then you pay for what you don't use. Indeed, and IIRC that's one of the reasons Rust removed its green thread implementation in the first place. > Or don't standardize on them and have a split ecosystem of half libs supporting use `green-thread.rs` and the other half supporting `rust-gthreads`. Don't forget the third lib for abstracting over the two!
