Hi everyone,

ok, let's in addition try out not unassigning anyone from tickets. This
makes it the responsibility of the component maintainers to
periodically check for stale-unassigned tickets and bring them to a
resolution. We can monitor the situation (# of stale-unassigned tickets)
and if the number of open stale-unassigned tickets is ever increasing, we
need to revisit this topic.

For reference here are the tickets for the adjustments:

* https://issues.apache.org/jira/browse/FLINK-23207 (PR available)
* https://issues.apache.org/jira/browse/FLINK-23206 (blocked by INFRA)
* https://issues.apache.org/jira/browse/FLINK-23205 (merged)
* https://issues.apache.org/jira/browse/FLINK-23250 (open)

Cheers,

Konstantin
