Comment (by TimothyBlynJacobs):

 Attached is an alternate approach that handles the filtering of the
 responses in the controller itself. This matches how the `context`
 parameter works, but it isn't included by default.

 This version also handles nested fields, specifying `title.raw` for just
 the raw title or `title` to retrieve both the raw and rendered title. This
 could also be used by controllers to only calculate the fields as
 necessary. I'm not sure whether this should be used to limit the fields
 queried ( I think that can be done in `WP_User_Query` but I'm not sure
 about the others ). I imagine some of the performance benefits here,
 besides response size, would be not filtering `the_content` if it wasn't a
 requested field, for instance.
