Schnorr signatures can be combined, allowing multiple operators to sign together. In a multi-operator system, the mint's public key would be the sum of the operators' public keys, and their signatures can be added together. This enables a setup where multiple operators, like two, can be required to sign, enhancing the security of the keys, which is a concern [From Followed User] notes that only signers care about.
