even worse, the neutral framing is just wrong, there isn’t a medical reason to treat trans people as their assigned sex rather than their actual sex, and in fact there are medical reasons to view trans patients as their actual sex and not their assigned sex (as I get into in my comment above).

There might still be other neutral framings that can be used to undermine trans rights, I think the trans athletic bans are a good example (though, the more evidence we get on that, the more it is looking to be the case that trans women on average are like cis women in their physical fitness and ability, not like cis men).
