if no explicit renderer is supplied, Elda should (probably) default to a JSON renderer
because the spec says

Conforming implementations MUST support the RDF and JSON formatters and SHOULD support the additional formatters in order to provide clients with additional flexibility in quering an API.

and RDF/XML does not seem to be a better choice than JSON.

Brian noted:

If I comment out the html formatter from the Elda config, Elda complains:

[[ HTTP Status 500 - bad specification: no renderer type for spec with
mime type text/plain ]]

I suspect this is part of that same problem.

I think you mean "no explict default renderer" (possibly). In which case I think that the JSON renderer as the default default renderer (as specified by the LDA specification) has long been the case.
