    Please keep the `timerTS` (renaming it to `initialTimerTimestamp`) 
parameter as an initial value for the `nextTimerTimestamp`/`al` field that you 
have added. Otherwise it's confusing where does this magic value `1000` come 
from and what are consequences of changing it.  Especially that you have kept 
the original comment `// the timestamp should be high enough to trigger the 
timer after all the elements arrive.` in the 
`testConnectWithBroadcastTranslation()`.

> Since KeyedBroadcastProcessFunction is about to get out of the door, I think 
> it will be great to expose the timer's key in KeyedBroadcastProcessFunction 
> too. If we don't do it now, it will be much more difficult to add the feature 
> on later because of user app compatibility issue.
