There are pictures of the brake-nut method here:

I agree that the OP's method is a great one--it matches the Miyata original. I wish I'd thought of it. But it's still kind of a pain--the slotted nut doesn't give a very good grip when you want to tighten the bolt. Of course, it's also a pain to have to carry a second allen wrench when using the brake-nut method, but it's arguably even more inconvenient to have to carry a slotted screwdriver.
As wonderful as the old Miyatas were and are, whoever was in charge of the company's binder-bolt division had some strange ideas. The worst setup of all was the one requiring a non-standard hex nut to fit the recess in the lug--break or lose that nut and you're really screwed. I'm eagerly waiting someone to come up with a good solution for that one. I have tried to do that and failed.
