Quoted from Guinnesstime:Why would Stern add the disclaimer if they're not going to use the disclaimer?
My guess would be, if a Pinsider freaks out because he has one tiny sliver of ghosting on one insert, and he wants an entire new populated play field, they can point to that and say nope.
Another Pinsider has 13 massively ghosting inserts and clear flaking, Stern will replace it.
Just my guess though. As stated, we will have wait and see.
