@dn3s If basic human decency weren't enough reason, it's insulting to the readers at this point too. Either we only know her by her current name, and the deadname is useless information, or we already know she used to use a different name and don't need it shoved in our faces again.
...actually I can't remember her deadname, come to think of it, so I'm not sure what that does to my point but I'ma call it a good thing anyway?
