No, -b is deprecated, you should be using -o backing_file=...
What description exactly are you talking about, qemu-img.texi? It says:
> @item create [-f @var{fmt}] [-o @var{options}] @var{filename} [@var{size}]

Which for me seemed to be a pretty clear reference to -o
backing_file=..., but if it isn't, maybe we can rephrase it somehow.
