Well I just thought it would be good to reduce number of attributes. I guess for transistors, logical symbols, resistors, capacitors, inductors and probably even micro controllers pin label would be enough.

pinname would only be needed if there is a need to distinguish between two pins with the same pinlabel within the same symbol. If there are for example two gnd symbols they belong to the same net could be considered as one pin in the netlist although design rule checker may check both are connected.


There should be no problem with several selectable sympol <--> footprint pin mapping either. Several gnd or power to one footprint pin also no problem. I also think it would be good to end up in a situation with a symbolic pin name and footprint pin only.
