It's not useful for wgpu right now, clearly, since WebGPU's views don't know about the usage. Other clients, including gfx-portability (via KHR_Maintenance2) can specify the usage per view, which allows both the Vulkan driver to make better decisions, and our DX11/DX12 implementations to avoid creating unnecessary SRV/UAV/RTV/DSV stuff.
