script deprecated (mongo 3.6 and up)?

In more recent versions of the ops manager documentation I’m not seeing any reference to where it can be used to add a secondary to a replicaset or create a new replicaset from the ops manager snapshot without having the secondaries run an initial sync by seeding the oplog with the same timestamp on both the primary and the secondary.

I’m wondering if this script is deprecated meaning it can’t be used in new versions of mongo as in version 3.6 and up?.
