And I don’t understand why docker is supporting this as docker + wasm makes no sense at all as wasm wants to replace docker as the runtime provider …
Constraints give you freedom because they allow you to make guarantees. Checksums, reliable test suites, and good software abstractions are all examples.

Those are runtimes, not languages. Here's a list of languages that compile to WASM: https://www.fermyon.com/wasm-languages/webassembly-language-...
IMO bash wouldn't make sense, but Java and Kotlin are there, as well as AssemblyScript, which is basically TypeScript.
