You (hopefully) state: "But the restorationist approach is artificial. It is inorganic and it won't stick."  I'm not so sure.  Obviously Pope Francis wanted to let the liturgy wars calm down a bit while he worked on other issues first.  And he sees his role to implement Vatican II (seeing as how he is too young to have attended any of the sessions) rather than explain or defend it.  Sadly, the insight of the bishops to recover the original "shape of the liturgy" from the accretions of the intervening centuries was never adequately addressed and explained to the people.  That is an omission that we may yet live to regret.
