We prefix any comment or request with "nit", as in "nitpick" when the reviewer knows they are being picky but it's still something worth mentioning. The coder in that case knows they can ignore that without consequence if their preference or perspective is different. The reviewer also knows that and doesn't feel bad if that advice is ignored. It's been helpful for me because I'm a picky reviewer and feel compelled to mention things that my years of experience tell me are "wrong." But I've also come to realize it's often not wrong, just not as good for potentially non-obvious reasons. But my devs will never learn the potentially "better" way if I don't point it out. So "nit" gives me a way to communicate and teach without the pressure of the dev needing to make an immediate change.
