While a general aftermath of how people are doing now is probably expected, I'm somewhat expecting Shigaraki actually gave OFA back to Deku in their fistbump moment and the ember he's feeling is the power settling back in and potentially stabilizing without the other influences. Concerns about people healing otherwise seem somewhat silly when Eri exists and just needs more time to grow her horn and better master the quirk. So, I don't really expect Bakugo to be crippled for long, either.
You're probably going to have some lingering criminal elements and other social issues to tackle in the meantime. The whole heteromorph racism thing kinda came out of left field and Spinner being touted a figurehead felt off. So, I think there's still a bit of work to do there as part of the healing process. Wouldn't even rule out things getting the Shippuuden treatment with an eventual time skip and new series.
