I’d say have it be a map to the first Jedi Temple, which Luke had been looking for when he disappeared. That way instead of the map literally being a record of Luke’s journey, the map leads to the place where the Resistance had logically deduced Luke would be.
In defense of AS, I think what he means is that a possible TFA reedit should only mention the temple, rather than have the map lead people to Luke himself.
However, if no one has any objections (and I’m very open to them), I’ll pursue the “covert agents tracking down Force-users” angle.
