I think adding a pinswap attrib to the schematic, not as part of the symbol library is a way forward to
annotation and netlists that agree with as-layed-out.

It would however probably be good if pcb could handle swap especially

I'd just handle it as:  do it, then output a netlist with .aslo, (as-layed-out), suffix.
Then you compare that to the bare netlist output from a gschem schematic via gnetlist.

Another form of gnetlist output I'd like is .net-heavy similar to what DJ's import tool
for PCB imports.  It would include all the net segments with symbol position center info, pads,
vias.  It would be used for a first cut at autoplacement, and for comparing to extracted layout netlists.

There's not any limit on how many types of netlist files with the same base name that are used except
practical remembering what they are for.
