To be fair, a Commoner has only 2 + INT mod skill points/level, and a Monk has 4 + INT mod. So there's at least a smidgen of value in the idea because of those extra skill points. (And, of course, taking Apprentice (spellcaster) will make UMD a class skill for anybody.) But yeah, apart from that smidgen of rationale, it's not synergistic with class features.
