Because I'm not familiar with how it works, and it seems does not have many use cases. I think this should not affect other use cases, because the code path should only be executed if queryable state is enabled. I think we should mention in the release notes that the new NAT support does not cover queryable state. This is an automated message from the Apache Git Service.

E.g., deploying a Flink cluster over machines from two different sub-network, each sub-network has multiple machines/TMs. TMs in the same sub-network might not be able to resolve each other's external address. Another example, multiple TMs on the same machine. I don't see a good way to cover all such cases.

Whenever the user needs to specify a bind port apart form the external port, the user also needs to set port forwarding rules in the environment, e.g. NAT gateway. For each external port, it can only be forwarded to one internal port. Therefore, it does not make sense to support a range of bind ports, because the user needs to know which internal port is bound anyway. This is an automated message from the Apache Git Service.

E.g., the none argument constructor of `ResourceProfile` must be private because the only case we need it is for constructing the singleton instance `UNKNOWN`. If we allow to create another instance of `ResourceProfile` with this none argument constructor, the created instance may not work properly. In this case, I don't see such problem in allowing direct access to the constructors. That makes hiding the constructors a nice but not must to have approach, by which we suggest people to choose the more convenient builders. On the other hand, it is not about how many efforts needed that we do not use builders in the test cases. Currently, the builder does two things: create a `ActorSystem`, and use it to create a `AkkaRpcService`. However, in many test cases, we need to use a custom testing actor system, which is different from the one we created for production. That's way we cannot easily use builders in the tests. We could also make the builder to support custom actor system. But that complicates the builder logics (what should we do if both custom actor system and the fields for creating the production actor system are provided), and I think it doesn't make sense to do for pure testing purpose.
