>Plus, as another poster pointed out, I think several other sports would be rejected for the same concerns if they weren't effectively grandfathered in.
There's no such thing as grandfathered in, events are we considered every olympics. Just because there is no world where the 400 m sprint will be removed does that mean it is grandfathered in. Wrestling was almost removed from the Olympics a few years ago. Which is one of the actual events from the ancient olympics.
I am aware, which is why I said "effectively." The bar for removing a sport is different than for adding one. For one thing, swimming and similar events have over a century of work making them more accessible.
Including most of the Winter Olympics.
