      Having a replSetHeartbeat command's ReplSetHeartbeatResponse include the node's oplog head time would allow oplog windows to be calculated from replSetGetStatus and as a result recorded in FTDC.

      For example:

      MongoDB Enterprise replset:SECONDARY> db.adminCommand({ replSetHeartbeat: "replset", configVersion: 6, from: "192.168.2.100:27019", term: 3 })
      {
      	"ok" : 1,
      	"state" : 2,
      	"v" : 6,
      	"configTerm" : 3,
      	"set" : "replset",
      	"syncingTo" : "192.168.2.13:27018",
      	"term" : NumberLong(3),
      	"primaryId" : NumberLong(1),
      	"durableOpTime" : {
      		"ts" : Timestamp(1642177853, 1),
      		"t" : NumberLong(3)
      	},
      	"durableWallTime" : ISODate("2022-01-14T16:30:53.341Z"),
      	"opTime" : {
      		"ts" : Timestamp(1642177853, 1),
      		"t" : NumberLong(3)
      	},
              /** Something like this maybe **/
              "oldestOpTime" : {
      		"ts" : Timestamp(1642177853, 1),
      		"t" : NumberLong(3)
      	},
              /**********************************/

      	"electable" : true,

      		"signature" : {
