The majority of Fortran users in HPC are ignorant of F08 (beyond trivial notions, eg existence) and will still be by the time of MPI-4. I think deprecating this function must be coincident with deprecating the pre-F08 bindings since it is ootebtionskly required for pre-F08 MPI usage. If we are serious about forcing everyone to use F08 (which I think is a terrible idea), then let's at least do it consistently. Jeff Sent from my iPhone

Would it still be ok to deprecate MPI_SIZEOF in MPI-4 (which is at least ~2 years away)? We don't have to have any plan for removing it.
I think that would be reasonable. In two years time more vendors will have implemented storage_size. And if it were well known that MPI wants people to migrate to this function, vendors would be motivated to add support sooner. The function itself is pretty trivial to implement as inline code by the compiler. It’s just a matter of vendor priorities.
