Most of the ideas come from the race being 7 feet tall, and a 7 foot tall bird would have a gigantic wingspan. That's why they can't fly while squeezing. We're not talking a lot sparrows; an albatross couldn't fly though a five foot wide hallway.
As a very large bird, they're gliders, not flappers. The restrictions are supposed to better model them, and allow for a more realistic flight speed than 120 ft per round with a dash (which is about 12 mph).
Combining slow fall, fly action, restrictions on gaining height, and a minimum stall speed would help package a lot of those restrictions into an easier to understand bundle.
