Circled back to this. Had a NPE from the new config that can be nulled out vs.
old. New PR + CI here:

> Revise timeout handling on queries triggering timeout introduced by
> CASSANDRA-7392
> ----------------------------------------------------------------------------------
>
> Key: CASSANDRA-17810
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17810
> Project: Cassandra
> Issue Type: Bug
> Components: Messaging/Internode
> Reporter: Josh McKenzie
> Assignee: Josh McKenzie
> Priority: Normal
>
> In situations where a replica times out with the code introduced in
> CASSANDRA-7392, they drop the timed-out query on the floor without notifying
> the coordinator; this doesn't become apparent coordinator-side until we go to
> serialize the response. While the results of this (i.e. missed data) should
> mostly be fixed by short read protection on repeat requests, the coordinator
> can in some cases throw an exception like {{IllegalStateException:
> UnfilteredRowIterator for keyspace.table has an open RT bound as its last
> item}} which is decidedly unfriendly.
> We should introduce a specific exception to allow replicas to notify a
> coordinator something has timed out and been dropped on the floor so the
> coordinator can appropriately handle that scenario and abort the query at
> that time.
