Well, it’s being used in English, so as long as the intended meaning comes across it can be all three and whatever else so long as it still communicates the intended message.
Yup, “Y’all” is the example I’d raise for folks who say it’s all AAVE, Y’all pretty firmly comes into American vernacular out of its use among rural farming communities, not necessarily usage among black culture.
Not to mention how a significant chunk of new vernacular is going to always be coming from the diasporatic distribution pipeline bringing new languages and dialects to America constantly. Granted this is mostly how new kinds of food enter the American linguistic pallette, but you get the idea.
