Is that an error?

Here's a simple schematic, with a silly useless circuit, many  
problems. It provokes *numerous* drc2 errors and warnings, but only  
two of them are real mistakes. And arguably, one should be able to  
duplicate connector pins for clarity within the schematic, although  
right now such usage doesn't netlist correctly. But drc2 misses all  
of the intentional errors.
