I think it's debatable whether WebGPU is less capable than OpenGL 4.6 with AZDO. Even if it is less capable, it doesn't mean WebGPU is not a solution nor only usable by browsers.
Regardless it's the closest portable solution at the moment, and it will continue to add capabilities. The WebGPU CG has already had public meetings with Khronos to talk about running WebGPU on top of Vulkan, and running Vulkan Portability on top of WebGPU. So I think there's a lot of interest in making WebGPU succeed on both web and native targets.
