  Despite a recent flurry of applications of the broadly defined
('non-AdS/non-CFT') holographic correspondence to a variety of condensed matter
problems, the status of this intriguing, yet speculative, approach remains
largely undetermined. This note exposes a number of potential inconsistencies
between the previously made holographic predictions and advocates for a
compelling need to systematically contrast the latter against the results of
alternate, more conventional, approaches as well as experimental data. It is
also proposed to extend the list of computed observables and utilize the
general relations between them as a further means of bringing the formal
holographic approach into a closer contact with the physical realm.
