I think the reader should preserve *all* of the information in a .sch file. There are several reasons:

1. Net connectivity depends on spatial information. But one approach doesn't fit all needs here. Right now, we have a simple minded netlister that reduces the net geometry in the schematic to a netlist model in which a net is topologically a single point. But suppose we start putting attributes on net segments ("this segment must carry 10A")? Shouldn't a back end for a layout tool that can handle this be able to see this, figure it out?
+1 from me. Gate drive sub-circuits in power designs come to mind, as well as Kelvin connections.
