That was never even legends canon. I always liked Legends' explanation that humans were indigenous to Coruscant
It was going to be. Did you miss the part of
@YellowIsACoolColor's post that said "

Alien Exodus was intended for pre-disney/eu canon (imagine using disney's Legends slave name) but the book got axed and reworked into a different novel trilogy that toned down the Star Wars connections as I already said in my last post but a few vague references lingered but with name changers in some parts, and that didn't stop the writers of the
Essential Atlas, Unknown Regions and
SW Encyclopedia or even Abel G. & J. Bongiorno from referencing factions from it and making connections to it, which would've been further solidified in unreleased novels like Cult Encounters from prior to the buyout, but only as in-universe myths or vague historical accounts to keep it vague enough so you could take what you want for those who get too butthurt about their childhood headcanons getting shaken up whenever lucasfilm of olde dared to explore anything in the setting (yet ironically the same bunch who use to complain then now lap up everything Disney Wars and now suddenly give a rats ass about "canon" because its full of queer bs, Ahsoka and Rey wank and characters saying curse words because they want SW to not even be itself anymore, a Buck Rogers-esque scifi fantasy adventure opera, just nostalgiabait, waifus and contemporary dopamine hits or simply praising everything that comes out because it has the disney logo), despite that the idea basically stemmed from George's own brand of autism via his
Monsters & Aliens book unlike Coruscant being the human homeworld which was always a vague connection that started as tie-in for the 70s comics which had Notron (later an ancient name for Coruscant) as the human homeworld, and even in later SW stuff which by the end its status as the human homeworld was always going back and forth to keep it vague, especially near the end as everything got muddled by Filoni retcons out the wazoo. However there was no doubt even since the early 2000s that Coruscant was definitely one of the first major human colony worlds since they drove off the original native Taung/ProtoMandalorians.
Even in the stuff released in the 2000s you have several worlds like Corellia also listed as the human homeworld alongside Coruscant and even KOTOR had HK-47 suggest the idea that humans were from Tatooine. Even blatant sources that try to make the connection more blatant like
NE Chronology keep the human+Coruscant connection vague by mentioning using "believed" and "maybe(s)" when discussing the human homeworld since human characters and other sources have them claim to have other homeworlds in multiple stories.

set in stone until late in the EU
Not counting in-story character mentions and back and forth sources (since even those are always from the biased point of view of the characters or are prone to change) only
The New Essential Chronology and
Coruscant and the Core Worlds really pushed the notion hard (especially when you take "Notron" into account) outside of story mentions which were released in 2003 and 2005, and the
Essential Atlas released in 2009 and onward outright stated that Coruscant in the ancient past prior to the Taung-Human/Zhell War was too cold to support human life, and the only later supplement to say otherwise was Galaxy at War but all it gives is a passing mention about how the Taung fought "native" humans invaders on Notron/Coruscant. So Coruscant being the human homeworld wasn't set in stone near the end, if anything it became even more vague or against it. And I say this as someone who would prefer Coruscant or Tatooine as the human homeworld but I've grown to like these unpublished novellas and behind the scenes crap the more I delve into them.
