That's a good question, about why they don't offer lean burn anymore.

The 5-speed Insight had an ULEV rating, even with lean burn: ULEV = "emits 50% less polluting emissions than the average for new cars released in that model year."

So I have to wonder if it was eliminated more for driveability/consumer acceptance reasons.

I think you made the right decision - that style is more likely to hurt MPG.

For comparison, Honda did put this drag-reducing spoiler on its 2001 Civic sedan. Most OEM drag-reducing spoilers on high-MPG cars are flush mounted, and fairly subtle, like this one is:
