However, there is a significant blocker to implement the proposed solution. Currently, the non-ConfigOption objects in the StreamExecutionEnvironment, CheckpointConfig, and ExecutionConfig have already been exposed to users through the public API. This poses a challenge when trying to modify the existing implementation to accommodate the proposed solution. Therefore, this FLIP aims to deprecate these Java objects and their corresponding getter/setter interfaces, ultimately removing them in FLINK-2.0.

Please note that this FLIP does not include deprecating fields related to serialization. The deprecation work for the serialization part will be carried out in conjunction with the relevant work in the FLINK-2.0 serialization section.
