CheckTemplateVerify Does Not Scale Due to UTXO's Required For Fee Payment

A notable concern is the efficiency comparison between CPFP (Child Pays for Parent) and RBF (Replace-By-Fee). The argument presented is that anchor outputs/CPFP are less efficient than RBF due to the additional bytes required for the CPFP transaction. This inefficiency is viewed as a threat to mining decentralization since using fewer bytes for out-of-band fee payments is preferable.

It's suggested that addressing the fee payment mechanisms before CTV becomes standardized is crucial. The aim is to prevent the establishment of inflexible CPFP designs, which would encourage out-of-band fee payments and perpetuate inefficiencies in the system. It is implied that there's an opportunity to refine the CTV standard to support more efficient methods like RBF for fee payment, thereby avoiding the drawbacks of the current CPFP approach.
