I've seen that dynamic and it lead to a group split, with the experimentalists on one side and a "we play DnD, and CoC" on the other.
It was quite amicable, but a lot of it was about people's investment of their time in what they perceived as worthwhile. Some people who only gamed once a week didn't want to play a "might be absolutely trash" game with their one session, and I'm not ill disposed to that reasoning in a short life*
