Fully Compatible
This is part of porting the SERVER-59409 to v4.4 branch where the build variant "enterprise-ubuntu-scanning-replica-set-monitor-1604-64-bit" is enforcing the functional parity.
In fact the scanning RSM is ignoring the setVersion in the ordering so the code has no feature parity but only the test compatibility parity. I was able to make the test to pass by porting a fail point from streaming RSM to the Refresher::receivedIsMasterFromMaster:
