Hello, We have some custom Flink sinks that need to use a batching approach, and we use timers to facilitate flushing. Currently, we’re casting the `RuntimeContext` provided by `RichFunction.getRuntimeContext()` to a `StreamingRuntimeContext` (which it always seems to be?), which then gives us access to `ProcessingTimeService` as a scheduler. Is there any chance of either `getProcessingTimeService` being added to `RuntimeContext`, or some other scheduling facility being exposed? With the runtime cast, if the implementation changes during an upgrade, our jobs can be completely broken without any compiler errors, which is a big source of exposure in our project.
