Well, there is one issue: iOS 4.3.3 can never reach 100% penetration. The iPhone 3G and iPod touch 2G don't get iOS 4.3.x, so they'll never get the "tracking" issue resolved, unless they jailbreak (voids warranty and unsuppoted). There are comparatively less of those devices out there at this point, but it's still a significant amount of devices. Eventually, Apple will have to resolve this. Not everyone updates their device every two years, and the number of each model they leave behind just keeps increasing. (This is similar to the fix for the browser-based jailbreak (JailbreakMe): the original iPhone and iPod touch will always be vulnerable, unless they use the fix available once jailbroken.)
