First,  this is debate mode not argument mode......

Sorry, bad example

At DC they are the same :-P

2GHz not so much...... I want my ground plane!

DB9 mounting tabs,  that's better,  I saw a SMA connector in my head as common enough for people to relate to with out firing up some drawing app :-P

Not true.  I would never use this type of connector and only connect one 

ground pin.  Add in the

parasitic inductance of the pins and then see if they are electrically 

equal.

Some discussion could be put into this.

do we want sub pins for the net of pins

so on a SMA example

the center conductor would be pin 1

the 4 mounting pins would be pins 2.1, 2.2, 2.3, 2.4

I don't see the necessity of this.  When I build parts with multiple

pins all of which I want connected

I give them different numbers.  There may be other types of examples

where this is needed but I've

never hit one.

The SMA connector,  do you have all four pins labeled separately, I wouldn't  or would I????????

pins 1,2,3,4,5 ?  

pin=2.*

would define in the symbol to attach all pins to the net
