  In that , I fully  agree!
  
  Though it has little to do with Pope Francis doing his job and revising some passages of Canon Law. No  claim to 'infallibility' about that.
  
  'Infallible' pronouncements are rather rare. Most of the job expectation of a leader of the Catholic Church doesn't require or expect 'infallibiliity'.
