That's totally fair, and I don't disagree. If someone's interested enough in the sport to purchase a dog specially bred for it, I don't think it's unreasonable to expect them do the right research and reference checks. They're probably already going to meets/trials to watch, and can ask handlers there for reputable breeders. That said, both of those sports have mixed breeds competing and thriving. I personally do agility with my mutt, although I recognize that I'd need a different dog and a lot more time/money to do really well. My point was, most dog owners aren't trying to compete at that level - in any dog sport.
