To be fair my bags looked OK when I bought the car but when I got them off and straightened them out I was shocked and so glad I did them. The bags fold over themselves and on mine the wear was sort of under the fold.
If there's no history of the bags being changed and they don't look new then I'd be tempted to change them as a preventative measure - unless you're not planning on keeping the car.
