Those boundaries are where we set them. Lots of people have made the change to treat transgender people as a regular part of society; here it’s as easy as referring to them by their chosen gender. It’s not like “he” and “she” were ever actually markers for genetic sex in opposition to social gender, but it would still be a simple change if they had been.
You can find this recommended all over the place. Standing against that, arguing that we should make people wait longer to be included when there is no cause for it, is what would make you awful. Please reconsider; it’s so easy in this case.
