Review Comment:
**Have not spent much time on this. But it looks like.**
- Hadoop gives all namespaces, Nessie too (being fixed), Dynamodb (code
looks like there is no level check. But I need to test it out. I am not sure
yet),
- glue & hive may be not applicable as it doesn't support nested namespaces.
- ECS, JDBC is giving only next-level namespaces.
- REST API spec has an example with just a 2-level namespace. So, cannot
deduce there also. But from the description maybe it also gives next-level
("certain level")

I can check more on this tomorrow.
