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.

Cheers,
Bill
