User blog comment:VeXJL/"If it ain't broken, don't fix it" is stupid and shouldn't be a valid reason./@comment-25368137-20170728234344

It isn't stupid, there's a lot of reasons people use this saying, although it is (overused) it still holds value. If you have a girlfriend who's a perfect match with you in everything, but you think going with another which may be more beautiful, but may have other problems of incompatibility, this applies.
