I assumed you meant empty list because that made sense. What you said here does not make sense.

That's because you're trying to snarkily jump into a conversation you don't understand.

User `flanked-evergl` is asking why do you need a whole new format for this instead of just using json. And the answer is because everyone needs to agree on how to specify the format in the json, which `crote` suggests is as simple as doing `{"schema": ..., "data": ...}`.

There's your format. If you want everyone to agree on the `{"schema": ..., "data": ...}` pattern, you can no longer accept just `[]` as a return type. Every response has to include the `schema` and `data` keys.
