> For pipelines that require the emitted watermarks to be absolutely correct
> the current behavior using 2 seconds timeout could lead to problems.
> Therefor it should be possible to disable this behavior. While changing the
> code the hardcoded 2 seconds can also be made configurable. (There's already
> a TODO about that in the code.)
>
> A (preliminary) PR making this change is available:
> https://github.com/apache/beam/pull/7382.
