I get what you're trying to say, but a lot of these ES6 things have been supported for longer than you'd think a while now, and are near-universal. Near-universal: not universal. But people still running very old devices or browsers are not going to have a fun time on many sites regardless, and WebGPU is not likely to be used casually on random sites: it will be used for the same stuff that WebGL and canvas is today: mostly for special-purpose things like games, some visualisations, etc. – the sort of stuff that very old and slow devices will have trouble with in the first place.
