I actually have a theory on why Twilight isn't immortal even though she's an Alicorn now: only ponies that were born as a pure Alicorn possess immortality, like Celestia and Luna. Since Twilight was confirmed to not outlive her friends, she doesn't have immortality because she was born as a Unicorn, who is then transformed into an Alicorn. The same thing can be applied to Cadance who, if the Crystal Heart Spell book is canon, started out as a Pegasus.
