I've worked in a place where reviews were obsessed with coding style. No one noticed serious bugs, but forget a space in the right place and you'd be doomed. And yet people still managed to rewrite stuff to their preferred style while managing to not violate any rule. No prescription about function and variable names? they'd change every single one their way. No prescription about argument alignment, they'd change it. Everything not esplicitly forbidden was an outlet to express their creativity or maybe tame their frustration.
