It has become reasonably clear that 46 XY DSD athletes are numerous enough [see the notorious all 46XY DSD 800m podium in the Rio 800m], and have a sufficiently material edge [see the recent 2k WR by a 46XY DSD athlete and next years's certain 200m WR by another 46XY DSD athlete] over the average women without that condition, that it's plainly a matter of time before the current middle distance rules are applied to the short sprints and also to long distance.
Other intersex slash obscure medical conditions can be treated on their own merits, they say nothing important about how we should treat 46 XY DSD athletes.
Re: trans athletes
I'm relatively relaxed about this issue. Trans athletes haven't yet made any real impact in top-level track. Part of the reason for this is probably that track and field careers are so short and that transitioning is usually time consuming - 'athletes' like Veronica Ivy and Laurel Hubbard only started competing as women by the time they were pretty much middle aged, most likely too late to really shine in track, unless they'd been world class in their past life as male athletes. I suppose I feel that the current rules seem pretty fair, maybe a tad generous to trans athletes but perhaps not inappropriately so given the trans population's status as a minority facing discrimination. I might start to get worried about trans track athletes as and when they start dominating female podiums or threatening to break female records.
