      In 3.6, an empty collMod is interpreted as an upgrade or downgrade command. However, just sending the server an empty collMod command creates an identical oplog entry. Initial sync is not safe with UUID upgrade/downgrade oplog entries, so it's not safe to log empty collMod oplog entries at all.
