Excellent point. There may be use cases where a DID tied to a verifiable history is a feature (particularly for organisations as opposed to individuals), but for most people having it linked to a blockchain is definitely not the way forward. Also, blockchains and associated protocols can become defunct, or dwindle in usage until a 51% takeover of the remainder is feasible, or many other things. I imagine that in the end, a DID will be a private/public keypair wrapped in some hardware that the average person can use.
