To be fair, you can test types as you parse JSON. But only a few.
The Avro schemas even include comments... huge win.

The benefit of having a schema associated with your data should not be

serialization format that has a schema (like Avro), you should choose the
later. The schema support alone will pay dividends over the long run.
