I have no opinions on this change, but all the people saying it would be difficult to implement are not correct. It would actually be quite simple. The game script (in English) already just has a bunch of variables that get replaced with whatever sex you pick when you create your character. All they would have to do is add something to the UI to let people pick from a list, and add those lists into the references. There is no need to edit the script itself at all, and it doesn't matter how long it is or how much they've added to it over the years.
