Just to address a couple other concerns, the Stray Fairies would have roamed free for that ending scene. That's minor. The hole? It's a game man. Link calls Epona w/ the Ocarina vast distances in an instant. If he transformed and used a Deku Flower to get back to Hyrule's Lost Woods, he wouldn't even have the blasted mask in a third Hero of Time installment if one was ever made.
