I'm with you. WebGPU has been used to compromise and fingerprint systems. Firefox (and related forks) are usually able to disable this kind of insecure fluff but it'd be nice if other browsers did as well.
WebGPU provides ZERO extra data that wasn't already available from WebGL in 2011. The world didn't end and it's been 15 years
On the other hand, disabling WebGPU is offering entropy for fingerprinting, too. A vanishingly small % of users will have done so.
