Probably out of reach for solving rigorously. A strong engine equipped with something like the opening books at https://katagobooks.org/ might well “solve” the game in the sense of always winning won positions and at least drawing drawn positions (if the komi value used makes draws possible). I suspect that always getting the best possible score (but without rigorous proof that that’s so) might be in reach.
