gEDA/gaf is and will be fully downwards-compatible, so any schematic that
worked with an older version of gEDA/gaf will work with a newer version,
as well. lepton-eda somewhat breaks that, but as long as you check the
netlist output for problems, you should be fine. So the attributes used
with gEDA/gaf 1.9.2 (net=, in this case) can be used as a compromise.

Oh no, please don't!

My preferred approach is to allow prefixing attributes with their
respective domains (pcb:footprint=, spice:device=, and so on) but
otherwise keep the existing semantics.
