By legacy, I believe you meant rte_atomic APIs. Those APIs do not take memory order as a parameter. So, it is difficult to change the implementation for those APIs. For ex: the add operation could take a RELEASE or RELAXED order depending on the use case.
So, the proposal is to deprecate the rte_atomic APIs and use C11 APIs directly. The proposal is here: https://patches.dpdk.org/cover/66745/
