I agree, it should only be applicable when the top-level entity is an array.

I am trying to move away from that approach, moving metadata to headers 
(ironically the offset and total count are the most common metadata items, 
and these are handled by the Content-Range header), allowing the actual 
content to be a "pure" representation of the resource, and therefore an 
array is the most natural top-level construct when requesting a collection 
of objects.
