Something seems off to me for those so against the idea. If it is useless or not needed isn't it safe to assume that you also feel many would not use the feature cause it is not needed? So where exactly is the fear for the option really stemming from? I do not think it comes from a place of caring about the devs work, cause their work would still be seen and appreciated by many. The reason behind why someone would want to use the option is also moot. Sure some may want to use it because they do not want to see a man in a wedding dress, or they do not want to see people in the frog or pig suits, or they simply find ones glam looks weird.
In the end their reason and use will not hamper your expression or experience. It will only be impacted if you either assume everyone uses the option or go out of your way to see if someone is using it or not.
Idk I just have a hard time thinking people are coming from a place on genuine concern if it was added. Seems more like people are up that their overall audience that will see their glam will be smaller and they cannot stomach that idea. Which I get, wanting to show off drip is part of the reason why many buy expensive clothing.
