Alexander,

These are orthogonal concepts. Users can certainly use them together, 
but there is no reason to merge them.

After all, threads attaching to the endpoints are almost, but not quite unlike helper threads given on "loan" to the MPI implementation. In the first case, the application is using the threads by itself. In the second case, the MPI is using threads for internal purposes. See the analogy? In both cases we let threads use or be used by MPI. Is this something one could possibly unite? They are being placed like on different sides of the boundary:
