Personally I also think that this vogue for imitating client-side js frameworks in wasm is a mistake - it would be nice to replace js in the browser and use the language used server side client side as well, but there's no need to repeat the mistakes of js frameworks which attempt to move all computation to the client side and replace the DOM entirely. I'd rather keep most of the work server-side (which is well understood, performant, and far easier to reason about), but use the same language for client-side work too where interactivity is required. These client-side frameworks are solving a non-problem on the vast majority of websites IMO.
