Must be new. Untill last Monday it wasn't.
So you know more, than I do.
I don't know, how you got your understanding of our Aikido.
Didn't Endo "play" at that seminar? Didn't he have one of his deshi with him?
I see my communication skills are very poor, I'm not able to make you understand my point correctly.
Please do an exercise: Go to Yoshinkai/Tomiki/Aikibudo dojo, regardless of affiliation. Then try to do your techniques on these folks following Endo sensei teaching(i.e. not grabbing attacker). Giving the fact you have 15 years of experience, you shouldn't face any problem.
Please report here the results.
