I think the style guide doesn't like two functions using the same name when it
takes different params (exceptions made for simple cases like char* and
std::string). Maybe GrantByIdIfRequested?

I think the styleguide allows for overloading in this way when the different
types are for convenience and the methods mean the same thing.
