The comparison between snow skiing and boarding is misleading. None of the alpine events were sacrificed for boards anymore than were the nordic events. There is in fact a lot of interaction and all three disciplines coexist in the Olympics even if at different venues (now there is an idea).
Any case the kitesurfers might be careful least they get their dream and the FSX equivalent of WS - here is the nub, while WS might have a shortish Olympic history its full potential as a sport in that venue has not yet been realised due to some curious decisions re designs around the limitations of venues and to fit into the traditional Olympic format rather than adapting to new forms of water sport. The best hope for change might be to insist on both disciplines being Olympic thus weighting the decision about format and location toward these modern sports (or split the locations) rather than the other way about .
