I still think this is a solution to a non-existent problem. Essentially interfaces solved this type of problem 30 years ago. Today you can implement a set of interfaces and, depending on your language of choice, hot swap / add/ delete them as needed and those can all do exactly what your fancy JSON does but without the proprietary, new syntax and language being introduced.
