Do you just want a wish list? How about configurable garbage collectors, cacheable JIT outputs, or a standardized bytecode format to facilitate language interop?
Those are great points. I asked because I have seen people get excited about new JS runtimes a lot when Deno came out, and not understanding that it was using V8 under the hood. So many people thought they wanted a "new TypeScript runtime" that would "compile to WASM" without really thinking through how that would work or what it would be. Spoilers: it would work the same as V8.
But thanks for those specific wishlist items, which are much more sensible! Isn't your last item WASM though, with its interface types proposal?
