Yes.  The real world concepts must exist, in a higher level.  In the
attributes.  The HIDs must implement them in a user-friendly way.  At
the lowest level, there shall be abstractions. 

The GUI must present footprints, vias, and hierachical sublayouts, both
in copy on write and in truly hierachical fashion.  But at the core,
they work all just the same. Then there will be no more question if some
feature is supported in elements or not, or how convoluted a via may be.
