I tend to agree with you but with one caveat. Said 500-1000 hour candidate should also either be an
experienced instructor, or an "approved person" with considerable background and a significant practical demonstration/test of his teaching skills.
Seem to remember back in the dim darks all this was taken pretty seriously with at the very least a B grade and a severe test before taking on ME or CIR.
