I have recently found out, that my rim brakes were slightly misaligned and the pads had developed an edge over some time and had worn a bit of paint outside the normal brake zone (see photos). It seems like a minor damage (I would say just cosmetics really). I was riding in wet conditions and the rims were very dirty, I suppose the dirt acted as an abrasive. It often happens to me that after riding a couple of hundreds of kms the brakes are not centered absolutely perfectly.
My question is, do you think that a similar situation (pads "overlapping the rim") in future might damage the rims significantly in terms of strength?
