Thanks for the review @StephanEwen.
You mean something like the `Executor` interface with the additional
methods for the scheduled execution. Differently said, removing the `Service`
methods like `shutdown`, `shutdownNow` and `awaitTermination` from the
interface?
That is a good idea. If we should stumble across the problem that a
component needs an actual `ScheduledExecutorService` implementation, then we
can still have a wrapper which throws an `UnsupportedOperationException` when
calling the respective methods. I will adapt the PR in that way.
