I'm very curious about isolation. Nvidia doesn't allow virtual GPUs on their consumer card drivers so this isolation feels like it can easily be abused. Will there be more support for vGPUs in the future? I hope Nvidia and others are pushed to include better isolation and vGPU support so that WebGPU doesn't need to do all this security isolation themselves. Your browser could theoretically request a vGPU instance to work on.
In general it would be great if browser GPU processes could operate on a vGPU, so the web as a whole would be isolated from the rest of your system. Right now that's not the case, so you're relying on drivers for that browser vs apps isolation, and relying on the browser to isolate tabs from each other as well. Both have failed in the past.
