There is a JS strings spec for wasm underway. https://github.com/WebAssembly/js-string-builtins

This feels so much like one of those cases where perfect is the enemy of the good. Node.js spent a decade being wrapped about the axle, convinced that cjs and esm could never work together. Ignoring that it worked great in standard-things/esm. But eventually Bun came around and that somehow made the case that all the hemming & hawing was nonsense all along, that doing nothing was worse than letting Fear Uncertainty and Doubt reign.

It just seems so unlikely that much of JS really matters for webidl. WebIDL specifies mostly structures and routes. It throws some exceptions but that doesn't seem particularly incompatible with wasm. WebIDL has promises, which is already pretty well solved by https://github.com/WebAssembly/js-string-builtins (which alas only Chrome seems to be moving on). GC is also in wasm now. I just don't get the defeatism. Fear Uncertainty and Doubt can be so seductive, anti-belief can be so fierce, and it sucks when things aren't perfect or when there's warts, but the paralysis here & anti-will seems so wildly disproportionately strong.
