Has Lucas or Lucasfilm ever made an official statement as to why Anakin's ghost was changed? It really doesn't seem like much thought was put into the change, especially when you consider the footage that was used and how it was executed.

As far as I remember, the justification was, that this young Anakin was a Jedi = good, while Darth Vader = old Anakin = bad and only Jedis can be seen as ghosts.

This is how I recall it, but that may be even complete bullshit besides the obvious lack of logic in this change.
