Not to answer for Stefan-L since I'm sure he has his own reasons (and please let him explain), but from my perspective don't take the name of the material "Legacy" as some type of old-school material workflow. Legacy materials behave just the same as most standard workflows, or even your standard V-Ray materials. The "Physical" material workflow is mostly for PBR and potential "Future" compatibility. This is why the Legacy material will "never be removed", since not only does it work with previous workflows it also has a more adaptable workflow for the artist, even if the artist breaks the energy conservation rules - which is why you cant control the Reflection color and other settings since they are meant to behave in a way thats not easy for the artist to break.
So in short, if it looks good, it works well, the author (Stefan-L) did a good job. Dont be so concerned about the technical aspects unless you understand it well and want to adapt it to some particular workflow.
Ah you beat me to it Stefan :D
