Its not unusual to want to tell if a user is a member of gods*. In my case I wanted to use it as a convenient flag to make an xml feed return some diagnostic data. Other reasons are to enable access to extra controls in various places for administrative purposes.
* this is probably the cause of me doing isGods() and and not isGod(). I think of it as a membership test and not as an attribute of the user. To me isGod() implies attribute, but isGods implies membership. Its only a point of view tho, I can see others not agreeing with this.
