If you skip the async stuff, Rust in WASM works quite well. I also found that Go has quite good WASM support. I think the "WASM as containers" and "WASM as .jar" approaches are rather silly, but language support is good enough to use the technology if you think it's a match. I don't think it will be for most, but there are use cases where pluggable modules with very limited API access are necessary, and for those use cases WASM works. Plus, if you want to run any kind of game engine in the browser, you're going to need WASM. While I'm not replacing my Steam install with a browser any time soon, I have found that WASM inside itch.io runs a lot faster and more stable than Winlator when I'm on my Android tablet.
