I'm not sure how you got the perception that we're going "all in" on green threads, given that the article in OP explicitly mentions that we're hoping to have an implementation based on stackless coroutines, based on this Zig language proposal: https://github.com/ziglang/zig/issues/23446
Performance matters; we're not planning to forget that. If fibers turn out to have unacceptable performance characteristics, then they won't become a widely used implementation. Nothing discussed in this article precludes stackless coroutines from backing the "general purpose" `Io` implementation if that turns out to be the best approach.
