I can only assume you are American. From what I see on TV that’s how they ride with just the back brake on their Harleys and the like. Correct motorcycle braking is done with mainly the front (strongest) brake and a little back brake to keep the bike level and balanced. Honda and BMW and probably others have linked brakes so that when you apply the front it also trails in a little back.
I am American but I got into the habit of rear brake bias while riding in Southeast Asia. So much metering of speeds in heavy traffic, and so much water, oil, and debris on the roads that are shared with 20 ton death machines that front wheel washout is a quick way to the afterlife (I've seen it and it's not pretty). Here in America though, if more than metering speed, I DO do my best to balance front/rear braking, though.
I don't understand how what you described is going to keep a bike balanced in all situations. The motorcycle safety foundation courses I've taken over the past year illustrate vividly the difference between balanced braking and biased braking. It seems like you're describing front biased braking and someone is going to have to explain to me the physics of how this is safer in all situations.
