:::::: I see no reason to believe there is agreement on a "signature's function" and what the line is to "wasteful clutter", or even that there should be an agreement on those things.  Editing despite the wishes of several others, even if in good faith, does not seem like "the essence of editing a wiki".  The mentioned edit is also probably not "several kilobytes" (I'm pretty sure it's less than 2KB, counting characters) - I think you are overestimating the extent of beneficial effects and the importance of this signature-refactoring thing.
