We should not change the checker sensitivity. It is very important that it
checks for binary compatibility - that was the promise of Flink 1.0.
If we want to break compatibility, we can define an exception rule to the
checker.
I think we should explore other options before. We can specify the
parallelism between `window(...)` and `apply(...)` without breaking the
compatibility. It would be a bit less nice, because it is different from how
the other functions do it, but it allows us to maintain the promise of
compatibility.
What do you think about that?
