Verification would require more data than CID itself provides (ipld document layout, chunking algorithm, max chunk sizes...).

Not providing verification would seem like a nearly fatal flaw would it not? If one cannot pass around IPFS urls and ensure that the content returned is the same for all users, it would make a great way to MiTM a target.
