Dawid Wysakowicz commented on FLINK-14059:
------------------------------------------
If we come up with a requirement to expose it to the user, we should do that
then. It's way easier to add a new config option than to remove existing one
from a public api.
I would be definitely +1 to move it to the StreamGraph (or other internal
structure).
