When I wrote all about concurrency I argued that all code should be async by default—like Go or Crystal—since there’s already so much implicit behaviour going on in your typical program, you might as well get low-cost I/O while you’re at it. I do think there are contexts where it’s useful to know that you aren’t going to suspend for an arbitrarily long amount of time, like a UI handler, and having the ability to write APIs that require no effects would allow these kinds of guarantees.
Implementers shouldn't need to jump through these hoops. When you find yourself needing to relax or bypass spec semantics just to achieve reasonable performance, that's a sign something is wrong with the spec itself. A well-designed streaming API should be efficient by default, not require each runtime to invent its own escape hatches.
