I don't think these availability annotations are currently available anywhere outside Darwin platforms. IMO it should be a part of a separate discussion about making availability annotations in Swift more broadly applicable for any non-Darwin platform, not just Wasm.

`WASI` could be a predefined "platform" (as in `#if os(WASI)`), but it could make just as much sense as a package or a module. In the latter case, in theory you can use `#if canImport(WASI, _version: 0.2)` today already: [[Pitch] SDK-conditional code - #4 by allevato](https://forums.swift.org/t/pitch-sdk-conditional-code/52642/4)
