It happens, and while not rampant, it's common enough that you need to watch out for it. I'm with you, perpetuating that kind of defect seems unnecessary to me.
I've personally seen it in Hollands. We took on a buck that had it from someone who was going to sell it for snake food once. We learned how to trim teeth with that guy and he lived to be 6. A quick search of el google doesn't show anything specific about Hollands like it did for ND though.
