Quantum gravity research desperately needs metaphysicians' help!

Here are some philosophers suggesting that metaphysics could be useful in the search for a final theory:

"it is precisely the fact that physics is not yet complete that metaphysicians right now have something to contribute. In expressing what they take to be the best ways of filling out current physics, of working through these theories' implications and trying to understand them, this can help the physicist better understand her own theories. Indeed this may give the physicist reason to favor one or another venue in developing and extending current theories and revising them."(Alyssa Ney: Neo-positivist metaphysics, 2012)

 "Let me also stress that metaphysics can be prospective as well as retrospective. It needn't only follow where science leads. ... And by exploring different conceptions of time, philosophers open up new possibilities to consider in devising a theory of quantum gravity." (Craig Callender: Philosophy of Science and Metaphysics, 2011)

"there is no shame in the fact that metaphysicians find themselves with a wide variety of acceptable theories for a given entity. ... having a range of conceptual options increases the depth and breadth of our understanding of the world, and should ultimately result on more successful final theories. If physics has a long way to go, it will need metaphysics for most of the way." (L. A. Paul: Metaphysics as modeling: the handmaiden's tale, 2012)

This is just ridiculous. Progress in fundamental physics will consist of mathematical innovation, doing more and more accurate experiments and developing new physical (not metaphysical) hypotheses and finding out ways to empirically test them. How on earth could metaphysicians, with their lack of practical know-how in experimentation and mathematical modeling, their scientifically outdated, metaphorical and untestable theories, their trout-turkeys and hypergunk, and their never-ending intuition mongering, make any kind of useful contributions to such a project?

Physicists are not and should not be interested in contemporary metaphysics:

"Physicists are aware that their subject raises many conceptual difficulties, but do not imagine that either a training in philosophy or a discussion of these difficulties with philosophers would help in solving them. ... Never before, I believe, have philosophy and the natural sciences been so far apart." (Michael Dummett: The Place of Philosophy in European Culture, 2012)

"the scientist seeking insights in pursuit of unification will find nothing of any use in most of the literature produced by analytic metaphysicians. ... Contemporary discussions ... are completely disconnected from his concerns because those debates utilize no information about the world that has been learned from any sciences. They may as well be occurring on regions of space-time that are space-like separated from those in which we ... sit; we recognize nothing in them that corresponds to any reality we can measure." (James Ladyman and Don Ross: The World in the Data, 2013) 

Ney's idea that metaphysicians could help the physicist better understand her own theories reminds me of this remark by Bas Van Fraassen:

"metaphysicians interpret what we initially understand into something hardly anyone understands." (The Empirical Stance, 2002)

 Lets leave the task of trying to understand physical theories to physicists instead of intuition-mongering non-physicists.
