Poor UV’s, they’re not doing anything wrong existing by default. If you’re not going to use them, there’s no harm them being there if you’re not even going to go into the UV editor. I guess it’s like renting an apartment and there’s a big flat screen TV on the wall there by default. I might say I don’t watch TV, I don’t need one and so the part of the wall with the TV flip’s around and hides it. Your wall is free to hang a painting and the TV wont bother you ever again. But it’s there if you need it, something might happen, maybe the internet goes down and now we have to go to the good old days of cable TV.
