Is there ever any merit in cutting down a lib to the essentials that a particular exercise needs....? Oh I dunno, example if you want one... cutting down MooTools to the essential elements needed by the mRotate script at http://www.piksite.com. Is there ever a scenario where it's worth doing... ever? Is it even feasible (or sensible)?
Yeah, this is one of those wildcard questions isn't it. It's a serious one :D, even if it's slightly mad.
