I don't understand how this is part of WebGPU - if we can't use the storage buffer class in shaders, we're downlevel no matter what as we always need to be able to write to buffers.

This extension provides a new SPIR-V StorageBuffer storage class. A Block-decorated object in this class is equivalent to a BufferBlock-decorated object in the Uniform storage class.

VK_KHR_storage_buffer_storage_class doesn't actually enable the use of storage buffers
