Have we had many instances where a project's community divided into
two camps and dug in to the point where they actually needed active
moderation? And in those cases, was the PTL not already on one side of
said argument? I'd prefer specific examples here.

I agree as well. PTL is a servant of the community, as any good leader
is. If the PTL feels they have to drop the hammer, or if an impass is
reached where they are asked to, it is because they have failed to get
everyone communicating effectively, not because "that's their job."
