Why are you counting these as part of meritocracy, rather than deviations from it?
(If they're sufficiently small deviations, you could still call the overall ecosystem a meritocracy. But then you have a meritocracy with deviations, and enshrining the deviations as part of meritocracy seems like a mistake.)
(I could also see an argument that "meritocracy plus it matters how likeable you are" would be preferable in many ways to just pure meritocracy. But "meritocracy plus it matters who you know" seems like a bad direction to go in.)
