It is no such thing. It is an appeal to keeping the site user-friendly. I believe tweaking everything for low priority reasons is more of a hassle on the average user than leaving some things be. For example, your proposed future revision: why block fanart? If an artist is credited and the artwork is removed at request, what is the issue? 's foolish. Nonsense.
Regarding the last line, yeah, that's what I said. So just doing a large revision for the sake of doing a large revision reeks to me. A wise man once said, "if it ain't broke, don't fix it". I don't think most of the things you're attempting to tweak are broken. Could just be me, though, I suppose.
