I'm not sure it's even good for snowballing, considering how relatively little gold it's worth; if you're in enough kills for it to make a notable difference to your game, you're probably ahead by enough that it won't really matter. Might have some use for 0 CS Supports, since they can usefully use just about every non-creep source of gold they can scratch up, but even then its positioned pretty deep in the tree, so you're looking at an, IMO, not very good value trade against whatever you're not taking (probably pulling points out of Utility.)
