I think we tend to use syntax like this now:

return GPUBufferCopyView { buffer->buffer().releaseNonNull(), *this };

> +void GPUCommandBuffer::copyBufferToTexture(const GPUBufferCopyView&
srcBuffer, const GPUTextureCopyView& dstTexture, const GPUExtent3D& size)

It's kind of weird that we can have a const destination just because ObjC.

I don't think this is a question.

You should consistently use .contains everywhere if you're going OptionSet<>

I think bufferA is SRC only and bufferB is both.
