      Done Arbiters must follow the same voting rules as data nodes regarding configTerm and configVersion. Add unittests in topology_coordinator_v1_test.cpp.

      Done Ensure we have tests that add/remove arbiters with non-force replSetReconfig. (Done in SERVER-46218.)

      Done Test that an arbiter gossips the config to other nodes including configTerm.

      Done Count arbiters as quorum members for Config Replication. Depends on SERVER-45085. Test: A PSA set with the secondary down can acknowledge replSetReconfig.
