I don't really like ENS (or any of the blockchain DNS facsimiles) for decentralized identity. ENS doesn't really have a story for verification of socials or other wallets, and there's no way to look up your ENS domain or eth addr from any of those other identities stored as records on an ENS domain.
Ceramic[0] (a sort of mutability layer on top of IPFS) solves this off-chain by using your crypto wallet to authenticate a DID (their DIDs are known as 3id[1]) which can have a list of socials and crypto wallets associated with them (using their IDX[2] system and the schemas called alsoKnownAs[3] and cryptoAccounts[4], respectively), and the validations are made possible by systems called IdentityLink[5] (verifies similar to Keybase) and Caip10Link[6] (sign a message with your wallet) (respectively). The Caip10Link also allows reverse lookup of a DID from a blockchain address. A reference implementation of these systems in action can be found at https://self.id/ .
Grain of salt: I'm working on a project that makes heavy use of Ceramic.
