DAY isn't very busy. My last flight through the DAY class C, they let me
fly right over the field at 4,500 using FF. I was expecting to be
vectored around but, all they did was give me notices of departing
traffic.


I think you're missing the point. DAY is busy enough to warrant Class C
airspace and in Class C airspace VFR aircraft must be separated from IFR
aircraft. Overflying VFR aircraft are typically assigned an altitude
restriction 500' above whatever is used as the initial altitude for IFR
departures.
