There're already games fully using SDF rendering, such as Dreams [0]. It even made a SIGGRAPH talk [1].

Whe SDFs are being used in games, SDFs don't really change the Analytical AA story much. SDFs are generally evaluated with ray marching, which is a form of discret sampling that has the same issue regarding coverage.

I think dreams might be using splats? It's possible that something like splats combined with a form of OIT along with an art style that is tolerant to certain types of artifacts could use Analytical AA. I don't know the specifics on Dreams, but i'd be surprised if even they would be using AAA.
