Well, come on, he is pushing the boundaries of orthodoxy, choosing his battlegrounds. He is canny enough to know that he cannot fight on all fronts. Communion for the divorced and remarried will go down well in countries and cultures where divorce and remarriage are rife, the USA in particular and other First World countries and he feels he can weather the storm.
There used to be a poster on Crux, Paul or Saul of Tarsus, a very avante garde commenter who used to end his comments with the words, "chip, chip, chip." He meant by this that every little 'chip' of the heterodox chisel would in time contribute eventually in the collapse of the edifice of Catholic doctrine.
My take is that Francis is slowly chipping away.
