Here's an example of how useful webassembly can be: we're at the (fairly early) stages of developing PRQL [1]. Because it's in rust, with WASM we could put a live compiler on a webpage [2], and recompile the PRQL into SQL on every keystroke.
There's no server process — it's all built in GitHub Actions, hosted in GitHub pages, and runs in the browser. The whole WASM code is 164 lines (o/w half are comments).
