This approach is intriguing as it introduces a mechanism where one can wait until all associated transactions or operations have expired before taking action. This method challenges the previously held belief that incorporating OP_EXPIRE might lead to inefficient use of block space, especially when paired with the requirement for a high transaction fee rate.

Such an application of OP_EXPIRE could potentially enhance the strategic flexibility within blockchain systems, allowing users or developers to optimize their interactions based on timing and expiration of operations. This not only questions the inefficiency argument but also opens up a dialogue on how blockchain functionalities like OP_EXPIRE can be leveraged to create more dynamic and efficient systems, especially in scenarios requiring tactical considerations around transaction timings and block space utilization.
