group_by_resource alone has a meaning, for example if nodes are explicitely selected (I was to get the total amount of that resource on [those nodes|that node]). It should not be prevented by code, because it leads to situation where providing just one grouping criterion causes no grouping to be done on final query, which causes in turn a SQL syntax error.
