Review Comment:
That would be interesting, though I'm not sure about adding that until we
have someone who will definitely implement using it.
We could phrase this in a way that metadata is currently optional. Maybe:
```suggestion
Metadata is either an empty string or a JSON string with an empty object.
In the future, additional fields may be added, but they are not required
to interpret the array.
```
