Has there been any thinking about how we would resolve a DID that has been re-anchored? Particularly where I think this is relevant is if I want to anchor a peer DID to a ledger later, or if a ledger dies and I want to port my data from one ledger to another. I know people have mentioned use cases of this in the past before, but I wasn't sure how it would be handled. My current mental model is that the DID method is how the resolver knows which ledger to check which seems incompatible with this use case.
