He tried walking that shit back, because it came down to scripting and not technology limitations:
"I badly misspoke if in an earlier statement I implied that any cut scenes between Rose and Leia were the fault of our VFX team and the wizards at ILM," Terrio said. "In that earlier interview, I was referring to a specific scene in which Leia's emotional state in Episode VII did not seem to match the scene we wrote for use in Episode IX, and so it was cut at the script stage before the VFX work was done. If we had chosen to use the scene, ILM would have made it look perfect. They always do. ILM performed actual miracles at every stage of the creative process in Episode IX. I remain in awe of their work."
The reality is, it's all a lie. In a crowded as fuck movie, JJ and this dude added a truly worthless character in Dominic Monaghan (WTF did he do?), and a random slug alien who went with the crew. We know there were scenes filmed where Rose interacted with Rey...where are those?
They specifically wrote dialogue where Rose fucking tells the audience she's been sidelined. The only missing thing would be for JJ's face to pop up in the screen corner, give a big Borat thumbs up, and say "You're welcome, 4chan!"
