Xiaogang Shi closed FLINK-5023.
-------------------------------
    Resolution: Won't Fix

The updates to the `State` interface will affect existing user code. We will not update the interface before Flink 2.0.

> Currently, the only method provided by the State interface is `clear()`. I think we should provide another method called `get()` to return the structured value (e.g., value, list, or map) under the current key. 
> In fact, the functionality of `get()` has already been implemented in all types of states: e.g., `value()` in ValueState and `get()` in ListState. The modification to the interface can better abstract these states.
