Could the same be said about CIELAB? As far as I can tell, there are a good number of spaces that are superior in every way, explicitly designed for that very purpose?
Yes. The expert advice is to prefer 1976, but people are in the habit of using 1931, perhaps because they don't know any better, or perhaps because "that's what everyone else uses".

Hi Jeff, as best I understand it, an important property of a chromaticity diagram space is that it be additive. i.e. that a blend between two primaries (or any other points in the space) lie on a straight line between those points. L*a*b* doesn't have that property, whereas Yxy and CIELUV do. You can certainly do projections of a gamut in L*a*b* space and they will be useful, but particularly in dealing with additive type devices like displays, it is a desirable property that you can reason simply about how primaries (or other points in the space) combine. Cheers, Graeme.
