No, for the following reasons

1.) allow the same C descriptor to be used in CFI_setpointer().  This is a 
bad idea to begin with, and will cause grief in compiler optimizers.
2.) there are apparent overlapping functionality between CFI_setpointer() 
and CFI_section().  It's confusing to understand exactly which does what, 
or when to use which.  It's also not clear to me which one will result in 
zero-based array section or one-based array section.
3.) allow Fortran ALLOCATABLE variables to be allocated on one side (C or 
Fortran) and then deallocated from the other side.  This likely will cause 
many implementation difficulties.
