I've never looked into GreaseMonkey so I might be missing some context here, but "cruft" sounds like it would be difficult to draw a clear consensus on.
Ads are relatively cut-and-dry. Wikipedia, at least as an ideal, is a collection of objective facts with citations. But "removing cruft"? I'm not saying it can't be done, but I think it would be tough to get a clear consensus within a community on what exactly that entails. Wikipedia itself has flame wars on half of its discussion pages over any details that are less than totally objective, and many that are. It works because the differences being argued about are usually small points that most users wouldn't really notice either way. If you're trying to get consensus on a hundred "bike shed" issues on each page... well, good luck.
It's a very cool and worthwhile idea though. I'd like to see whatever might come of this after a few iterations.
