Well here you have the open book era. Through The Clone Wars and The Bad Batch we now have all sorts of pieces in place, and we have destinations and consequences of some pieces known from Solo and Rebels. Now we just get to see where the pieces that survived Order 66 and the Clone Wars go before Rebels. We know Maul will be shadow running Crimson Dawn. We know he will eventually end up stranded. We know Qi'ra will have been at least someone trained by Maul enough to attempt to enact revenge against Palpatine and Vader in the aftermath of the Battle of Hoth. We know Ventress is out there. We know Quinlan Vos is out there. We now The Path is out there. We know Ahsoka is out there and will be joining up with Bail Organa's cell in the near future. We know there are still rebelling Clones out there working to get more of their brothers away from the Empire that is tossing them away in favor of Stormtroopers. We know the Empire is slowly growing as they start getting their new Imperial Star Destroyers online and replace Republic weapons of war with Imperial weapons of occupation. There is a 14 year or so gap between The Bad Batch and Rebels that can (and likely will be) mined for stories. I doubt only with Maul. There are plenty of other things that can be done, btu Maul is an instrument to show the way.
