IMHO this format is more readable and clear. AFAIK, we used the previous
format to reduce the complexity of the JSON definition and make it less
nested. This made the parsing logic complex, made the application
definition less intuitive and less readable. In real world, we might rarely
come across situations where we need more than one or two levels of
recursion (nested groups). Therefore, +1 from me for this change.
