It sounds to me like you are proposing deprecating point to point in MPI and using the one-sided operations as the primitives? I think this is still wrong because you still have no ability to combine different one-sided to do proper scheduling,

Use neighborhood collectives for that. I think point-to-point is still occasionally useful for setup and probably for certain kinds of unstructured communication, but usually just used once.
