More volume absolutely creates the opportunity for burping, and rims being wider is only a partial answer - I think what AJ nailed with this is that the tire construction needed to come along and get beefier to take advantage of it, but instead the weight weenie answers of 'more volume less carcass' is what sold initially, but that same set of problems described are why 'plus' tires are going out of vogue, but somehow e-bike tires in 'plus sizing' are becoming an extant thing, and for pure gravity bikes that aren't strictly about speed, they're an amazingly good answer.
The tire inserts create a lot more changes than just displacing what would be compressible air, but I suspect that's part of the situation that is why the tread-peel of being on an effective camber is less noticeable there, it's not that they're adding side support so much as making any compression in a side-loaded situation result in less overall lateral displacement of the contact patch.
