Oh, and though WIT can be in-your-face in these tutorials (as we try to leave a good offramp for folks to customize beyond the quickstart) WIT shouldn’t be necessary for most common use-cases. There are standardized interfaces that language toolchains may support out-of-the-box, e.g. TinyGo supporting wasi-cli by default with the wasip2 target. If you use the SDKs in wasmCloud or Rust crates like wstd, then the interfaces are selected automatically since they’re being used behind the functions in the SDK itself. It’s meant to be lower level and handled by toolchains and library developers.
