A lot of people mean QP-like semantics when they talk about "RDMA", rather than the RDMA operation itself. I.e. pre-posted receive buffers associated with a particular user-space process.
That aside, conceptually, I see little difference between RDMA semantics versus the facility that you describe. The main difference is the complexity of the header and the checks done against it.
