Its way cool to have a cue maker or cue company say hay collarless shafts are prone to crack and there is no warranty we will still make and sell you one but no warranty .
That way the customer knows the risk up front, and not back doored after the shaft breaks.
Personally when someone sells a collarless laminated LD shaft and doesn't warn the customer and just adds the no warranty at the bottom of their warranty pages I don't feel the seller is being 100% honest to the customer.
