>One predicted use was social recovery, which is using Taproot to back up your coins with help from your friends. The people making that prediction knew Taproot inside out. They were wrong. Five years on, I'm not aware of a single consumer wallet doing social recovery with Taproot.
For the past three years, @Liana Wallet has offered SafetyNet, allowing you to designate a service or friends during wallet setup by providing their xpubs. Their keys can later after a relative timelock runs out act as cosigners or as a signer of last resort if needed.
