Consider that for the UMD release verification tests (where these
cross-compatibility are tested) are not exhaustive, only in a
production like environment all the use cases are covered. Based on
the verification information, MPI were the only service having
problems with mixed WNs. But, as I wrote, a direct experience in
production would better clear most of the doubts.
