Good for headcanon but bad for actual canon. I wish we could just get a super definitive answer from someone like Kathleen Kennedy or from a canon source.
Why would Kennedy be a more reliable source than Hidalgo?
For a “definitive answer” you’d need to get it from either Lucas or Kasdan (or Kesher if he every talked about it before he died).Because in this instance he pretty much used a non canon source. Doesn’t really sit well with me.
EDIT:
I’m curious as to what WEG writers means…
WEG is the abbreviation for West End Games, the writers of which actually fleshed out more Star Wars EU and continuity in the 80s than anyone for a long time when writing their guides for the original Star Wars PnP RPG. A lot of old EU books were based on their timelines and maps and canon.
