I've heard multiple time this kind of argument on the field, but soon or later, these clusters actually had a split brain scenario with clients connected on both side, some very bad corruptions, data lost, etc. Do never under estimate the kaos. It will always find a way to surprise you. If there is a breach somewhere, soon or later everything will blow up.
