What is the release status of WebGPU? Seems like it changes so fast that browser support , i.e. Firefox nightly for example, is spotty.
They still have WGSL semantics to sort out, and there are a couple of issues postponed for post MVP 1.0.
At least now Chrome Canary for Android has WebGPU support as well, no need to mess with Vulkan directly.
(And in FF nightly, it's more like "not enabled, no ETA" than "spotty")
Speculation: The spec is still a Working Draft aka: comments welcome from anyone, may drastically change. Chrome already intends to ship soon. It's quite possible that Chrome is rushing ahead as usual even though the spec hasn't been fully finalized.
