Your argumentation is clear, but...

.. Eagle may have some inpsiration for us. In eagle, when you do pin 
swapping, the symbol is not altered, but the wires connecting to the 
symbol are changed. They often run diagonally afterwards and you have 
to change the schematic to clean up things.

This is not a perfect sollution but one that would enable geda to 
perform this task, too.

Of course, changing the data structures to cope with swapped pins 
without rearranging the graphics would be neat and no mechanism should 
be established, that blocks this way in future version.

73, Mario
