Oh, that was embarrassing :-) Yes, it was the discussion from two weeks
ago about passing empty strings as BlockdevRef that made me think that
this would be ugly.

Anyway, was this ever implemented? It seems that passing a string to the
'backing' parameter is only specified in the JSON schema, but no one
actually uses that.

So I'll implement that for the next version of my series.
