Dynamic Address Generation: The approach I've used isn't about static address combinations but dynamically generating addresses through key tweaking. This means the address for each transaction can be unique and created on-the-fly, enhancing privacy beyond what static multisig setups can achieve.
Efficiency and Broad Applicability: By not relying on the multisig structure, Txtailor avoids the added transaction complexity and costs associated with it. This efficiency is inherent and applicable across Bitcoin and other blockchains too( which may not use space saving techniques available via segwit)
you do know that in taproot to spend a TR, you have to reveal the spending conditions leaf hash is part of the merkle root.
yes cores protocol of cludgy code miscounts witness bytes to appear smaller, but the real BYTE data is not as small as a wallet will tell you
also in old method each TX can customise to a new multisig recipient or change the message, thus changing the hash of send 'key'.. to then cause there to be a new multisig, so not sure what you are on about as static multisig setups
