I would like to point out that in this outline there is no mention of another apprentice for Obi-Wan, and it seems to be a big and obvious point that Anakin and Vader are the same. In other words, if the prequels were made then, they would not have kept the secret that Vader is Luke's father. In other words, there was never any intention to do so. In other words, the conception of the episode numbers meant that there would later be prequels to tell the backstory, not that there would be prequels to just start the story earlier. In other words, yeah, I'm making an argument about a popular fan edit idea.
