Im not crazy about the idea of "requiring" things. But I see your point-to an extent.
But to require such things is kinda/sorta like "requiring" motorcyclists to have training wheels,until they can prove they know how to ride.
Now, if they wanted to add some training to the existing classes to cover retention training in more detail,maybe.. but to create or add more classes to be able to get a permit? No thnx.
