It's that little things that count. If the frame doesn't have braze-ons to attach a rear rack, at least two water bottles in the frame triangle, and (optional) attachment points on the fork for a front rack, Its a fail for me. Racks are just sooooo convenient to have and don't weigh that much. I know they give a bicycle a 'Fred' look, but that's OK with me.
That's my opinion and I'm sticking to it.
