Is this a new term? I thought the term was just “config shard”.

Starting in 8.0. MongoDB introduces support for embedded config server shards.

``mongosync`` supports sync from dedicated config server sharded clusters to
embedded config server sharded clusters and vice versa. Additionally, ``mongosync``
supports sync from replica sets to embedded config sharded clusters.
