I'm not advocating for comma separators... But having multiple top level JSON elements separated by a coma is equivalent to processing an array structure. The initial [ and the closing ] are implicitly mapped to the connection/stream/etc. start and end events. It is just a minor token replacement at the top level between elements, which could be layered into some existing tooling. From this point of view, I would imagine the retooling is minor for either use case. It does mean tools need to be depth aware.
