Query: Remarks on the Heavy-Quark Flavour Symmetry for doubly heavy hadronic
  molecules   The possibility for a common effective field theory for hadronic molecules
with different heavy-quark flavours is examined critically. It is argued that
such a theory does not allow one to draw definite conclusions for doubly heavy
molecules. In particular, it does not allow one to relate binding energies for
the molecules in the c-quark and b-quark sectors with controlled uncertainties.
Therefore, while this kind of reasoning does not preclude from employing
heavy-quark spin symmetry for charmonium- and bottomonium-like states
separately within a well established effective field theory framework,
relations between different heavy-quark sectors can only be obtained using
phenomenological approaches with uncontrolled uncertainties.
