I think the safety concern starts with the 22" model...it holds a bigger fuel load and has the potential to get hotter underneath than the 18" model. So they add a heat shield to the 22" as a safety feature, then decide to add it to the 18" model, also.
Remember that today's WSM is basically unchanged from 1981. The world has changed a lot since then...from a safety standpoint, we don't design things the same way we did 25 years ago, whether it's a car, a crib, or a cooker. We can argue about whether or not that's a good thing (let's don't), but it is the way it is today.
It's true that I never heard anyone explicitly ask for a heat shield, but there are examples of people placing their cooker on top of pavers to protect a wooden deck...there are photos of this on TVWB. Maybe it was this observation that caused Weber to pay attention to this, in addition to any temp measurements they may have taken beneath the cooker? (I don't know if they did take temp measurements, but it seems logical that they would...if I were building a heat shield, I would want to measure before and after to see how well it worked.)
Regarding bugs, I'm sensitive to that issue, too. We'll see how it goes with the shield. I imagine anything in there will hop out quickly once the fire is started.
If you were to install the aluminum shield and decide later you didn't want it, it would be easy enough to remove without taking off the legs...just snip it off using tin snips. Of course, you might also come up with a mod that makes it removable. (Just don't tell Weber...)
