A little lateral motion in one’s backswing is not an issue unless balance is compromised. If the weight moves to the outside of the trail side (right for righties) foot, the only way to transfer the weight back to the left side for the down swing is with the upper body getting involved. That alters the natural path for the club, creating an over the top move. So, if your balance is good, don’t worry about it–freedom, rather than rigidity–is a good thing.
