He's a tree, he could totally be in TotK. But what if he's not? Like, Korok seeds were a bit superfluous, especially after a certain point, but I think I'll miss them if Hestu's not in Tears. There are surely other options for gating inventory slots and other ways to make the world feel full and alive (come on Piccori!) but don't you kind of want Hestu to return? Shalaka!
