We need it if we sometimes want to use MPI without PETSc (which is not
unlikely even if PETSc is the default).

MPIManager works like PETScManager and takes care of the global
initialization at startup:

  MPIManager::init();

and also calls finalize() automatically when the program exits. It
talks to MPI to see if it has already been initialized (by PETSc,
itself or someone else) and does nothing if that is the case.
