This would allow for minimal fees and the use of CPFP, which is currently not possible due to CSV delays on outputs. However, this would require P2SH as a raw 'OP_TRUE' is non-standard. To address this issue, Jorge Timón questioned the practical difference between sending to op_true and giving coins as fees directly. The proposed solution involves sending 0 satoshis to OP_TRUE to create a UTXO, which would then be spent with a normal fee. The miner would need to confirm the original transaction with the 0-value OP_TRUE in order to receive the latter fee. It should be noted that the template-script idea does not make it mandatory to spend in the same block, but rather the UTXO would cease to be valid after that block. Additionally, the 0-value output would not take up a UTXO db entry when left unused.
