Yes. I have a chip with 4 x 4mm legs spreading from the centre just outside the arc of the drivers wiper so just away from the 'A' Zone that means a 10mm chip is allowable. I had it repaired by a local guy that drilled it out and put some resin in it. Cost me £50 (gave the guy pound notes) and that was over a year ago now. It has lasted fine, not got any bigger, passed an MOT, survived the frosts and not caused any damage to the wiper blade. I can recommend a repair over a replacement if it can be repaired.
