Description
I think #549 and WebAssembly/wasi-threads#48, present a qualitative change, however minor, from 'just an imported API' to where WASI would need some core features. I didn't think this should've prevented #549 from going forward, but I think it would be good to start a discussion on this.
In my view WASI is taking these dependencies on upstream standard, we can debate whether one is causing the other or they are independent:
- Component Model itself is a core proposal, at least far as APIs are concerned
- Certain features must be implemented in core wasm instead of APIs, as we have seen with threads
This is concerning, because so far there is not much traction in supporting component model or other core features mandated by the current WASI direction in browsers (treads draft hasn't been presented yet, for example). This would create divergence between WASI and 'stock' web environment, while more convergence would be preferrable in my opinion, as there are currently some challenges with running the same code both ways.
