On the one hand, I think this is quite unnecessary, since you can put a tile and resize it to have it as a background. This is just my opinion.
But, on the other hand, we would have the advantage of not being able to move the background accidentally in the editor (which happens sometimes), which could be useful, although not really important at all.
