You go through and hide all the composites marked as a "via".  For pcb
to deal with vias differently doesn't mean that vias needs to be
something fundamentally different than a footprint.

From my reading of this conversation there is a disconnect between
what people are talking about w.r.t. words like the "core".  Some are
talking about the "lowest internal levels" where a via can just be
another composite object.  Some are talking about everything in pcb
besides the gui, where do you need to distinguish a via from a
footprint.  While others seem to be using "gui" as everything but the
"lowest internal levels"
