This is an interesting question.
Do you think TKD contributed greatly to the martial arts. Many say TKD and it's McDojo tendency epitomise what is wrong with martial arts. But many people who cuss TKD often started their martial arts in TKD.
As of Wushu in Olympic, no, I don't think it's a good idea. As far as "Olympic" Wushu goes, it's just gymnastic adopted to martial arts. Open Pushing Hand competition is much more productive for the martial arts in the long run, IMO.
