But that's the issue. People co-opted the ACoA terminology, which IS correct, for ACoC, which isn't. There is nothing "advanced" about CoC coating. It's just basic Haki flow + CoC.
ACoC is only rare, because the amount of people who have control over their CoC is tiny. Even guys like Zoro and Kid have not been shown to have good control over it, and they are >>> YCs.
Again, my point is they are just different applications of CoC. It's not one above the other.
For example, this is an advanced version of Haki blasts/crowd control
"ACoC" is not the evolution of "basic Haki". That is ^. "ACoC" or coating, is just a different application of CoC.

Adv coc =\= Basic COC + Adv coa
Coating COC has never said to be simply using basic coc with adv coa.
