Flew out of Orlando yesterday. We boarded first as elite so I didn’t actually see any baggage policing, but there was a baggage handling ramp guy waiting at the gate to (probably) stow the policed checked bags. I do not recall seeing a ramp guy ever at a boarding gate before.

So the baggage police thing is probably a planned, coordinated corporate thing. It has to cost Frontier actual extra money to have the contract guy waiting there.
