I wonder how many commercial flights get kicked out of the IFR system "because we're a bit busy"...

Commercial flights operate IFR in class G airspace. They drop out of the airway system into destinations like Inverness or LondonDerry in IMC.
So maybe your question should be "do commercial flights fly IFR OCAS ?" The answer is YES even the 737s of this world.
I am leaning towards getting rid of all the Jepps Aerads with the hateful task of updating them and going to something like a couple of I Pads with data and hardcopies for enroute charts departure destination and alterantive airports only. Everything else as data on computers
