Then again, I wouldn't be surprised if Scootaloo's wings were the *real* reason "Growing Up is Hard to Do" got pushed back until near the end. You've got one group of fans holding her up as a role model for people with disabilities, and another hopeful to see her fly eventually after watching her struggle. Plus Faust's claim that she "hadn't figured it out yet" after initially conceiving Scootaloo as having a bona fide disability (suggesting that the higher-ups thought that giving her an explicit diagnosis of "grounded for life" would be too much of a downer).
So there would likely have been strong pressure to avoid making waves in either direction.
