Probably needs to be fixed by bundling runtimes for things like Go, or bringing back cross-website caching in some secure way if that's possible
replyThat's an orthogonal problem. First it needs to be possible and straightforward to write GCed languages in the sandbox. Second, GCed languages need to be willing to fit with the web/WASM GC model, which may not exactly match their own GC and which won't use their own GC. And after that, languages with runtimes could start trying to figure out how they might reduce the overhead of having a runtime.

replyI think most languages could pretty easily use WASM GC. The main issue comes around FFI. That's where things get nasty.
WasmGC doesn't support interior pointers, and is quite primitive in available set of operations, this is quite relevant if you care about performance, as it would be a regression in many languages, hence why it has largely been ignored, other than the runtimes that were part of the announcement.
