Actually, IMO, this is amazing. The bathroom stuff is great enough, but really, letting transgirls use girls' restrooms is no big deal for anyone. I've gone into hundreds of ladies' rooms and have yet to actually see anything that someone wouldn't want me to see.
Locker rooms are a totally different story. Students get mostly or totally undressed, and stuff is out there for the seeing.
Personally, as fascinated as I was in high school with anything female, if I had transitioned at that age and been allowed to use the girls' locker, there is NO WAY I could have stopped myself from stealing a glance at whatever I could whenever I could.
