Hard disagree. "More discussions once more opinionated developers join" is universally true regardless of which frameworks/philosophies you start with. The point of convention being more important than configuration is that it reduces those conversations, because you can rely on the conventions as a default.
If an opinionated developer thinks a different configuration is better, then that helps form the conversation immediately. Everyone is already familiar with the convention, so the discussion only needs to inform everyone about the pros/cons of the alternative.
