DXF/DWG is too complex and changing too often for current size of comunity 
which could potentialy create free DXF/DWG library.

They can but only some 2 latest versions if I recall well.
I have written here (the last paragraph)

No, it can read latest DWG/DXF via v.in.dwg (OpenDWG) which can be used for any
work by any organization. Unfortunately it cannot be distributed with GRASS
and users have to compile it themselves.
