They're never going to retcon anything about KOTOR. They never have before, and they won't start now. They prefer to skirt around the questions of what actually happened with everything important in the KOTOR era. The closest they'll ever come to information on the KOTOR era besides vagυe mention in sourcebooks and other such material is the comics, in which they follow the stories of the uninteresting, cookie-cutter characters that nobody actually cares about (like Lucien Draay and Zayne Carrick), rather than the ones that actually made KOTOR worth caring about.
"Grant Allen [...] had written a book about the Evolution of the Idea of God. [...] it would be much more interesting if God wrote a book about the evolution of the idea of Grant Allen." ~ G. K. Chesterton, The Everlasting Man
