Some kind of 'development' events for trans people might be a nice idea. Even just to promote sport among them and make the field strong and big enough to continue the debate on making specific rules for each discipline to make it possible for them to start in main categories. Because still, they should have a right to compete within the strongest field if they meet certain criteria.
Also maybe a change in understanding the categories would help, so trans people competing won't be that kind of a taboo. I mean, change "men" and "women" categories to something more inclusive. Like "male-leaning"/" female-leaning". I'm not sure how to call it suitably, but I hope you get the idea. I suppose that would be welcomed by non-binary athletes like Leo Baker.
