In other words, for "mere mortal", everyday process and most PANTONE ink colors, X-Rite's method would not be better suited than Graeme's or KM FD series or -- gasp! -- Techkon latest Spectrodens generation?

Graeme is precisely correct, the KM FD series, i1 Pro2 and i1iSis 2 are using a modeling process (as does Argyle and i1Profilers OBA module), the eXact uses instead an approach using filtered Tungsten with additional sources in the UV to provide the spectral power distribution at the measurement plane. Either approach is completely valid for OBA’s as they are well studied and modeled. The issue comes when you look at other potential fluorescing agents. Then the model may, or very likely may not, perform as expected and thus the eXact is the better choice for these more complex situations.

please forgive my technical ignorance but is there anything fundamentally wrong or flawed in the following approach :
It's a modeling approach, the same in principle as used by ArgyllCMS FWA compensation, and the i1pro2 M1/M2. You calibrate for the media's fluorescent response by measuring with the instrument light sources, and then use a model to predict how it will look under a real D50 spectrum.
