Wheel is the group used by OSX for the 'system' /Applications. It was present since at least 1989-03-13 in the source of BSD Unix. Whether the connotation is 'big wheel' or 'wheel of fortune' is unclear from my sources, but membership of wheel is special. In OS X PAM is used to set the policy that su (1) will use. There always will be OS versions that arent' supported on your system and won't install or work properly. For full freedom and tinkering, one could go Linux but there a distributions that run an a Mac as well. But those can be less stable and the problems you might run into that are pain the you know what to solve.
