Not sure I follow? The parent poster was asking about "well, isn't it an issue with your TSL definition of 'DDL schema access' if you can store data in JSON or EAV so it doesn't have a 'fixed schema'", and my answer is: No, that's fine. Just like it would be fine for you to store or use binary/blobs/arrays/whatever. We've seen some crazy/cool use cases like developers storing binary 3D lidar data in TimescaleDB. In fact, with these "right-to-improve" changes, you could even modify the database to embed custom logic inside TimescaleDB to handle your protobuf format (as opposed to UDFs or application code), and it would still be permitted.
