I've seen gender neutral bathrooms but I don't think I've seen bathrooms for trans people specifically. Well, that's inefficient; trans folk make up, what, 1% of the population if rounding up?

I could also see some might feel "outed" by having to use them, instead of any and all using a gender neutral option well-designed for privacy. Trans peeps get the same access as everyone else, my cis woman self also wins by having bathroom cubicles that don't have an inch-wide gap around the door. (I think this is what intersectional allyship looks like 🌈🙌, /s sorta)
