At the very least I don't think most of us would claim the PLC relying on a central (if limited in power) registry is ideal. I think a lot of us have somewhat accepted that this is just the price to pay for the features we need out of a good DID method. If we want a DID method that is "strongly-consistent, recoverable, and allows for key rotation"1 then the options are a central registry or blockchains ... no?

An interesting step towards a properly decentralised DID method.
