It’s not misleading to measure the performance of WebAssembly in a web browser.
But as already mentioned we have gone through this all before. Maybe we'll see wasm bytecodes pushed through silicon like we did the Jvm... Although perhaps this time it might stick or move up into server hardware (which might have happened, but I only recall embedded devices supporting hardware level Jvm bytecodes).
In short the web browser bit is omitted from the title.
