The big utility of WASM for me, like OP hints at, is bringing things that would be infeasible to port to the web to it, like, say https://pgaskin.net/kepubify/ https://pgaskin.net/kepubify/ and other conversion tools (eg ffmpeg-wasm). Much preferable to downloading something or uploading a file to some random person’s server
