If it's just a UI modification, I don't see the big deal. Awhile back, SE left in a functionality that let you enlarge text in message bubbles (not something you can do from settings). It was awesome for low-vision players like me. Then the next patch they stopped your ability to enlarge that until enough people were like "hey I kinda need that back" and they added it back in. So if this is a popular mod that somehow simplifies a process (I'm a console player so I have no idea what it is or does), then I'd imagine SE would want to look at what it does specifically and how they can integrate that into the existing UI.
