Yes, I understand how to do shorts with NET= attribute

Yes, it's a classic heavy symbol. It's a standard header wired up for a 
standard bus -- by creating a heavy symbol a lot of clutter and tedium 
can be removed since nearly every design I intend to do for the near 
future will use it.  Not to mention "correct by construction" wiring -- 
and since minor goofs can lead to various kinds of power supply shorts, 
it seems like a good idea to bury/automate the details.

Yes, I'm doing basically that. I wrote a header symbol/footprint 
generator that I am using for generic headers. After running it through 
the project and getting some PCB's back I'll be releasing the code.
