It certainly has an impact on heavy workloads that replicate tables with few modifications. It receives a high traffic of 'begin' and 'commit' messages that the previous Postgres versions have to handle (discard). I would classify it as a performance improvement for logical replication. Don't have a strong opinion if it should be mentioned or not.
