> The separation between {{registerInputOutput}} and {{invoke}} in {{AbstractInvokable}} is an artifact of previous Flink versions. The {{registerInputOutput}} method used to trigger the creation of input and output gates. This has become obsolete as the task itself takes care of this now and {{registerInputOutput}} only requests the input/output gates.
> The contract of having a single {{invoke}} method, which cleans up after itself is easier to implement than applying it to two methods.
