Slightly ninjaed, whilst trying to phrase this post to my satisfaction, but... In a (very much) non-contact sport, that I'm involved in, various competitions didn't even allow women for quite a while... and there were separate membership bodies even after that[1].
Recently it's been posited that women's and men's results in events that they have for decades been co-mingled (performances excepting) should be separated again!
That there have been women who have outperformed the men, rarely but notably, and that the prizes have been equalised (by value and extent) with the prize-listings often side-by side-by-side, doesn't seem to matter. The stated aim is that the first women, overall, might be dispirited to be found down beyond the first dozen or so men in the combined result-order list. But then there are age-classes in which the young and old categories only win out against those in more traditionally prime age-ranges in a very few exceptional circumstances. All I can see is an attempt to resegregate everyone again. (Perhaps even with a crafty eye over seperately listing trans competitors... it has that kind of smell to it. And, given that this bit is at least relevent to the thread subject, I might as well mention that.)
Of course, there are many subtle complications to all these issues. And historical inertia combines with any reactionary counterpush, either for or against what any given somebody might think is the proper natural situation....
[1] Related: Reading about the history of bowling the other day, apropos of nothing much else to do with this subject, it seems the Professional Women's Bowling Association only merged with/filtered into the PBA in 2003, but has re-established itself as a separate body in again in 2015 (IIRC). Though this seemed to be more for financial/sponsorship reasons.
