Yep, I second that motion. Putting a no-erc directive on an usused pin is a reminder to me that I have thought about that pin and decided it should be unconnected. Otherwise, how do you know that you've gotten around to thinking about that pin? It's easy to forget pin assignments in the age of super-mega-pin chips! Another thing I do is make ALL pins visible - even power and no connect pins. This is important because modern chips have so many screwy voltage requirements (+1.8, +2.5, +3.3, low-voltage-of-the-week, etc.) and different grounds (analog gnd, digital gnd, etc.) that you can't leave that up to the old-time hidden-power-pins-automatically-connect-to-power-ports-and-nets game. Funny how those nifty old automation features get obsoleted by complex technology!
