Oda cares very little about any strawhat but Luffy post ts. In his mind all there dreams are pretty much irrelevant beyond how they can help Luffy achieve his dream of becoming PK and overthrowing the WG. He likely lost his interest in the crew around the MF saga, where he had Luffy interact with some of the most important characters of the story, while the SHP did filler shit with bums.
In Oda´s mind, having the Gorosei upon their introduction fight and struggle with Strawhats would just be an insult beyond belief to them, same with Kizaru. Maybe at EOS, but before that, in Oda´s mind, it makes more sense for the strawhats to be saved by an ancient robot, and Joyboys 800 year old Haki. They´re just not characters allowed to have achievements that rival Luffy in his mind. Oda barely even gave the supernova any achievements that could compare with Luffy, and they´re captains of their own crews.
