Feature Request: Friendlier extension JSON for non-standard JSON consumers

[sttawm]

Currently, this project's JSON printer produces complex and deeply nested json for extensions (as per the standard). It would be nice if the printer produced a simpler JSON, for i.e. clients that were willing to accept non-standard FHIR.

One could imagine running the standard protobuf json printer to simplify printing of extensions, but then again the overall JSON becomes more complex (with lots of nested "value").

Have you taken a look at the output when using the analytic schema (kFormatAnalytic in the C++ parser)? It is designed to promote Extensions to first class values, and limit recursive depth.
