I see this claim quite a lot on reddit and YouTube video comment sections too, but never with a source for it, or any relevant quotes on it from the high ups at Lucasfilm on the subject. Hate to be “that guy”, but do you have a source for that?
First, they wouldn’ve have done it by now. Pre-TLJ, Lucasfilm’s agenda under Disney was to appeal to the fandom that believes Lucas fucked up Star Wars. No Prequel content, TFA being OT fan-service palooza, cancelling The Clone Wars in favor of Rebels, the hyper focus on the OT era in comics and novels, etc. Even now in the age of Prequel apologetics, they still reference the OOT (the OG Krait Dragon call being used in The Mandalorian Season 2).
I highly doubt that with JJ Abrams and Jon Favreau clearly favoring the original versions, they wouldn’t have released them by now if there wasn’t something stopping them.
Second, we know JJ Abrams asked and was told it wasn’t possible.
