Most definitely agreed on that. You'll have people like that anywhere you go. However, due to the nature of those these chains are built, they're pretty quickly flexible. That's the beauty of the witness structure, they can come to a consensus on forks pretty quickly and without much (any, really?) pain.

That, and I feel like the team(s) behind these technologies are not the type of folks who enjoy stagnation. They're innovators. I feel like they'll always gravitate toward the best tech, that's what I do anyways. Study; make best judgement; commit.
