If I create a bind group layout with buffer bindings A, B, and C. If a shader only uses buffer A, then it would be nice if I could bind a GPUBufferBinding with size 0 for slots B and C, however, the steps for creating buffer bindings don't allow for zero-sized buffers:

The bound part designated by bufferBinding.offset and bufferBinding.size resides inside the buffer and has non-zero size.

This strikes me as an unusual requirement; as long as the matching pipeline's minBindingSize is 0, I would expect it to be allowed.
