It can leave an uneven or damaged contact surface. The cookware's condition should be assessed separately from whether it still heats.
What the observation means
Loose material or rough edges can mark glass, while a distorted base may affect stability. A food-contact coating issue is also a cookware question.
A useful next step
Keep damaged cookware out of use until its manufacturer advises whether it is suitable. Do not sand the base or cover damage with an adhesive patch. If marks or a crack appeared on the hob after contact, stop and seek appliance assessment rather than simply changing the pan.
