Yes, that is my point, but in past tense. It
could have been done when the resort was built. And just like you are speculating why it wasn't, I am speculating as well. I just don't see how it was because of a safety concern if they built pools, a playground, viewing areas close to the savannas, etc. It could have been zoning issues, wanting more emphasis on the savannas rather than providing this type of exercise, or who knows what else. My whole point is that I just find it odd that AKL/AKV is the ONLY resort on all of Disney property lacking this amenity. It just feels strange that I might one day go to a value resort for an amenity that my deluxe resort is missing. When I bought in, I did not walk as part of my daily routine, and I did not take resort days on our vacations. Now that I do both, I miss this aspect.
As far as Alien Encounter, I never rode it, so I don't know what I missed out on. As for Stitch, my family actually liked it. I guess I am odd in more ways than one.
