Not if it's deprecated.  If it's deprecated, nothing new will be included in mpif.h.

The path forward for such an app would be to use mpi3 for the parts of their app that want to use nonblocking collectives.  That was the explicit goal of having INTEGER<-->Fortran handle conversion functions (i.e., legacy apps that include mpif.h/use mpi, but want to add some MPI-3 functionality).
