To carry the "too complicated" argument (much) farther, and only partly
tongue-in-cheek, the MPI Fortran forum should identify the 20 or so MPI
functions that are adequate to link 99.9% of all Fortran programs using
MPI, and completely delete the Fortran interface for all the rest. The
0.1% power users can easily figure out how to write their own wrappers
and interface blocks to access the other C library routines directly.
Had C interoperability in Fortran been well established at the time MPI
was started, I would hope that there would have never been separate
Fortran interfaces in the first place. This would be a big step in that
direction, and would have minimal backward compatibility effects on the
vast majority of users. Obviously, I'm not suggesting this as an
immediate change to solve the current problems, but I think it is worth
