Like they say at worst WASM can make a mess of it's own data. The selling point of WASM outside of browser to me is native modules for other languages where you can whitelist the exposed APIs (and provide sandboxed versions) while having cross-platform binaries. So for example in the future node can ship with WASM module support and JS can load a C WASM module binary which I can deploy on Windows/Linux/Mac, and I can review what that module has access to via some module manifest, and node WASM exposes wrapped POSIX API based on manifest configuration.
