Why a hole exists in Ford truck/ van column-mounted ignition cylinder faceplate?

Does anyone know why a hole exists in Ford truck/ van column-mounted ignition cylinder faceplate?

It's there so you can remove the ignition lock when necessary.

Hole for DVD, make boy go he he he

It releases the lock cylinder when it's in a particular position. But the key has to be in the ignition to do it. There's a tool for this but if you straighten out a paper clip or stiff piece of wire it will do the job.
