Nowadays those French NPs would be analysed as DPs, determiner phrases. Anyway, it's not that there are no constructions in any labuage that are difficult for endocentricity; it's rather that endocentricity is so overwhelmingprevalent and so much more restrictive than exocentricity that syntacticians take endocentricity to be an essential feature of natlang syntax.
