Yep, we use Electron specifically because it gives us a locked-down version of Chromium with a consistent WebGPU implementation. Without that, we're stuck dealing with whatever browser version the user happens to have, and that completely wrecks the stability of our GPU pipeline.
Okay, fair, none of the apps I had in mind make much use of WebGPU and it stands to reason that browser diversity might be a bigger problem with a very complicated and relatively less mature API like that one.
