| There are little (to no?) situations where su has a good reason to check wheel. You either have the password, or you don't have it. But not something in-between. Outside of any ideology, in a scenario where you use su to become root, it's a very odd choice to link the wheel group to su;
because if you know the password to the "root" user, and you have physical or remote access to the computer, you can likely just login as root. And if you can't, then it means you actually needed sudo su, not su. Those who actually need to be root, usually use sudo instead of su. In the other cases, if you just need to switch user, then no point at all to refer to wheel |
