The rule there is that it doesn't matter how many style guides you have or tools to auto-style your thing or whatnot people will still find something to nitpick and argue about.

If the Convention Manual says all sheds shall be green they'll argue about what shade of green. If it says it should be Magellan Green they'll argue about whether it should be clear coated and what grit should be used to prepare the surface. It never ends. They'll argue about whether the window frames should be the same color etc.
