Even in the most recent arc, Luffy is still open to recruiting people and Oda hasn't given the confirmation that the Straw Hat membership is closed either, in addition to others like Vivi and Yamato who've yet to join back up with the crew after what they said. This doesn't even have anything to do with time either, since as far as I'm concerned, anyone can join up at any time. So long as the writing is done well, and Luffy's friendship prevails, then the time is irrelevant.
Also, worth mentioning automatically relegating someone to the Straw Hat Grand Fleet isn't always the best option either, since people wanting to support Luffy most directly would be farther away from him. It's why Jinbe isn't relegated to the Grand Fleet for example, because then he'd be too far away.
