No, it's primarily a problem for classical music. It's disconcerting (dis-concerting?) to hear an orchestra or string quartet set up in a mirror image.
As for drums, I don't think it's generally a good mixing practice to have them spread out on the left and right. It can sound cool in a sound-effect-y sort of way, and sometimes that can be an artistic choice, but you get a stereo image of a drummer that has arms about eight feet long. This detracts from audience-perspective recordings, jazz combos, and the like.
