Description

See https://github.com/apache/kafka/pull/5567#discussion_r214188984 (please keep the discussion on this Jira ticket).

There is an opportunity to use a slightly different naming strategy for suppression nodes so that they can be moved around the topology without upsetting other nodes' names.

The main downside is that it might be confusing to have a separate naming strategy for just this one kind of node.

Then again, this could create important opportunities for topology-compatible optimizations.

 

At a higher design/implementation cost, but a lower ongoing complexity, we could consider this naming approach for all node types.
