You're thinking of MuSig(2), which is indeed a cool watly to do multisig. I'm talking here specifically about using CHECKSIGADD in taproot *leaves*. Different thing.
The taproot change included *both* Schnorr sigs in BIP340, which enables MuSig2, but also script trees, which enables the selective revelation I mentioned above.
