GM Question: Nostalrius 2.0 Stance on Model Editing?

So with the recent announcement that Nostalrius will me merging with Elysium, whats the Staff's stance on texture/model editing? I know that using external programms on is bannable, but lets be real here. These changes would be purely cosmetic and would also only affect the user, no one else. They dont give you any gameplay advantage whatsoever
To show you what i mean have a look at this example video

As you can see the changes are purely optical and nothing else is touched
