I don't think pixels have an id or a geometry, they are not actually
features
It would be great to have the layer name there to identify the requested
layer and the returned value..
but you already now the layer because you have just requested data from
it?...
Just like if the INFO_FORMAT is application/vnd.ogc.gml
the gml does not provide the layername and if you look closely does not
provide a fid or a geometry, so the behaviour is the same for both types
of response.
