      A transaction-ending error is thrown in additional participants when readConcern on a request does not match the transaction's readConcern.

      During getMore, the readConcern can differ between router and shard, specifically in afterClusterTime.

      Max notes that although readConcern is included in requests, compare-equal should only be enforced on the first statement of a transaction that the participant processes, not on subsequent statements of the transaction.
