Pope Francis says the liturgical reforms of Vatican II are irreversible, and puts his magisterial authority behind this statement.
The article says there is still room for "rethinking the reform", but also notes that the Pope has discouraged the concept of "a reform of the reform".
As I'm not a traditionalist, this doesn't hit me as hard as it's going to hit a lot of others. But I still worry about the effect it will have. I'm amazed I only learned about it incidentally, a half an hour ago, when I visited The Catholic Herald website.
Post-script, a little later: OK, perhaps this is not as big a deal as I thought it was at first. I have not paid as much attention to liturgical controversies as other people.
