Fareastdriver, you take us back. Most of us used to fly with the breakers pulled following a few rundowns in less than ideal circumstances. We took no notice of the edict which came, from the FAA I think, that on single engine aircraft the overspeed was to be disabled, whereas on a twin the overspeed was to be used - both single/twin edicts were mandatory. Figuring that the overspeed trip was more or less equivalent to having an engine failure we were unable to discern the reasoning behind the single/twin logic, and still flew with the breakers pulled.
