Because when it constructs an AS-REP, the KDC gets to choose which of the 
user's keys will be used, subject only to constraints the client provides 
about what enctypes it can handle.  There's no way for the client to say "I 
can't handle the AFS string-to-key; don't use it", so the KDC is free to 
choose that key.
