Sorta. The Last Jedi apparently had an easter egg reference, a kyber crystal he used, and the Rakata and their empire are specifically referenced in Andor.
Which is a small continuity problem since it was a literal plot point of Kotor that it has been so long the galaxy had mostly forgotten about them, but whatever, the current consensus is Revan’s general story is canon if not necessarily specific events from the games.
Flavor text on an easter egg item doesn’t break canon, it’s really just the devs speaking directly to the player
If there’s one thing Star Wars does well, it’s applying a history to every single fuckin thing on screen. In this case the multiple references to the Rakatans makes it fairly likely Darth Revan will be outright canonized eventually, especially because there just really isn’t a point to the Rakata without his plotline.
Like, what, we’re supposed to give a shit they maybe made Centerpoint Station?
