This has led to some controversy, with critics warning that the changes could raise barriers for new node operators and reduce decentralization. Despite these concerns, the continuous development and upgrades to Bitcoin Core demonstrate a commitment to improving the network's functionality and resilience. The scheduled v30 upgrade will allow multiple OP_RETURN outputs per transaction while deprecating user configuration controls over data limits. Node operators would lose the ability to restrict arbitrary data inclusion through local policy settings.
