because the postprocessing codes need some serious cleanup but nobody  
has (yet) found
the time .and. the will .and. the knowledge to do it. In the  
distribution under development
there is a TODO file, like in all self-respecting software projects.  
Inside it:
4.4 Cleanup
   4.4.2 Avoid monster routines that do too many things at the same time
         depending on the value of too many variables. An example:
         read_file [...]
A recent problem with postprocessing and nonlocal DFT belongs to the
same category, by the way.
