WebGPU is a new W3C standard for 3D graphics in the browser, loosely based on modern graphics APIs such as Vulkan, DirectX 12 and Metal.
Right now only Chromium-derived browsers support it via Dawn. Firefox supports it in nightly builds only via WGPU, but the support is incomplete and so is not enabled in stable release builds.
Resolution criteria
An announcement in the Firefox release notes is sufficient for this question to resolve. Supporting a single OS and CPU architecture is enough - e.g. only on x86_64 Windows still counts.
If support arrives in June 2025, then options 2 and 3 will resolve YES, while options 1 and 4 will resolve NO.
I will not bet on this market.

Relevant info from today's WGPU release announcement:
We anticipate many breaking changes before we fully comply with the WebGPU spec., which we expect to take a small number of years.
