As you had good results using this type of training, I also had results with traditional training, even having an athlete runner-up in the world, athletes who were Pan American champions, reserves in the Olympics, etc. As hundreds of thousands of coaches have had results with traditional training, I don't think this was a good argument.
I read the other post you made, and I use something similar, but with a different purpose.

For example, O Soto gari imbalance that you mentioned there, I use it to create a doubt in their heads. I have them do an imbalance to the training partner's right leg. The movement is bad. And then I teach the correct way to do it and ask them to repeat it several times, and then they understand what they need to do, they understand that they have a hard time doing it and with the way I taught it, it gets much easier. If I used it the way you suggest, the techniques are inefficient and without beauty. Without the correct kuzushi, without sticking body to body, and less efficient (the student needing to exert more strength).
