I wasnt saying its a good idea, but having invisible pins indicates that 
you want to connect to something that is not visible, its literaly there 
in the name. An invisible pin.

I mean, otherwise there could be a stacked pin instead. Im not saying 
that invisible pins are good practise, but thats not really for me to say.

What is silly is having invisible pins working as no-pins except if they 
are a stacked pin, well that doesnt sound clear to me.
