This seems to be the path followed:

systemsetup pointed to the Admin framework.

Admin framework analysis revealed use of "createFileWithContents". The function in which this use occurs is not named in the analysis.

An error message in the initial proof attempt led to "authenticateUsingAuthorization". Back to systemsetup to determine how to use "authenticateUsingAuthorization". (This is where I ended up mentally relinking the issue back to systemsetup.)

So, I concede that is is not stated where within the Admin framework this "createFileWithContents" method is invoked. However, I also agree that if that function was not used, it would be simple to remove it and the issue would be fixed.
