Disney has canonized the Rakatan Empire so for now it’s assumed all the Old Republic works and timelines are canon(ish).
The Old Republic was actually 25,000 years old, I misremembered, but there was a period about a thousand years before the OT it was dissolved and then a different Republic was formed that… did everything exactly the same?
The result is people largely ignoring that stumble in its timeline.
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
