Aljoscha Krettek closed FLINK-5061.
-----------------------------------
       Resolution: Not A Problem
    Fix Version/s:     (was: 1.2.0)

After some discussion it seems this could still be useful for some cases.

> The Trigger does not do what people think it does. The problem is that a watermark T signals that we won't see elements with timestamp < T in the future. It does not signal that we have not yet seen elements with timestamp > T. So it cannot really be used to trigger at different stages of processing an event-time window.
