Beat the game without collecting/using propeller

When you open a new file and watch the Princess Peach getting captured cutscene Mario is already facing to the right on the world map (after the cutscene is over) But when you select a file where the cutscene is already watched Mario is facing down. (On the world map) So, wouldn't watching the cutscene be a small timesave? (Although watching the cutscene every time you fail would be annoying but a timesave in a speedrun is a timesave)

Since super Mario 3D all-stars has no difference from the original other than the BLJ being removed and BLJs are banned on 70-star runs can I do 70 star runs on 3Dallstars and submit them for the 70-star category?
