Anon - I see this lay advisory commission as a step in Francis figuring out how to bring lay influence, secular scholarship in psychology, sociology, and modern world thinking and lay lived experience, into the power structures of the Vatican.  This one is not working as it needs to work to influence cardinals and high Church muckety-mucks.  Rather than ending the work, I think Pope Francis needs to recognize that the form of an advisory commission is not working and change the structure, give it more power, and require dicasteries/congregations to work with it. 

But, yes, Pope Francis needs to act and not just let this all pass as if of no consequence.  He needs some sharp words with the heads of established Vatican groups - starting with the CDF but including other congregations.
