The Struct type is similar to some of the other well-known types like
Timestamp and Duration which have their own custom JSON representation (see
here <https://developers.google.com/protocol-buffers/docs/proto3#json>).
I'm afraid there is no easy way to replicate that functionality with a type
other than Struct.
