The problem is that not all grid universe job types need an x509  
proxy. Currently, if X509UserProxy is defined in the job ad, Condor  
assumes the proxy is required by the job and must be present. So we  
want condor_submit to automatically add X509UserProxy for job types  
that always need a proxy (gt2, gt4), but not for job types that don't  
necessarily require one (condor, non-grid universes).

Once you do match-making, condor_submit has no idea what type the job  
will eventually be, so we can't have it set X509UserProxy  
automatically. Users who's jobs only match with condor-c resources  
will be surprised and annoyed if condor_submit tells them they're  
missing a proxy.
