Well, technically the fact that FFG came out with a Zero move maneuver doesn't prove that it's not a stupid idea... Unless you couple it with FFG is incapable of stupid ideas. Note - I'm not saying that it is/isn't a stupid idea, just pointing out that it could still be debated. I know from a gameplay perspective, it's a good addition. I'm not sure I'm sold on it as far as a real world application. But at the same time, it's silly that an A wing can do a 5 straight, and then turn on a dime the next turn, or an X wing doing 4 forward, and then 1 forward. But I put all of that aside (along with the stop maneuver) when playing the game because it's still loads of fun, and wouldn't work as well if there was a hysteresis to your maneuvers.
You make a good point sir. I meant "stupid" in the sense that FFG would never do it or that it wouldn't work in the game. Personally I love additions like the 0 movement. There are only so many variations you can do of a dial before it starts to feel like "its been done before" so adding the 0 really made the Lambda different and i think a good addition to the game, even if there are problems with it from a logic standpoint
