This may also give way to same sex pairs.
Could in theory. There’s a pretty narrow range of physical characteristics for skaters who tend to be successful at the highest levels of pairs skating, and statistically, one set of characteristics is more common in people who identify as women and the other set of characteristics is more common in people who identify as men. And there are still not a lot of out trans and non-binary people in skating. (Nor will there be any time soon; this thread alone is a proof that we’ve got a long way to go to make the sport more inclusive.) So on a practical level, I wouldn’t expect elite pairs skating to look a whole lot different even if the language in the rule books is modernized.
