For what it is worth, I am not in favor of this change. I like the Lando introduction and his exchange about sending Leia his love. Sure it is overly nostalgic and perhaps interrupts the pacing a tad, but without this scene then Lando is definitely nothing more than a glorified cameo in my opinion.
It was the “send Leia my love” line that really annoyed me. They never followed it up. We never saw them together, yes Carrie died before filming but they had plenty of option to give us a heartfelt farewell with Lando by her deathbed. That would have been beautiful imo but now it feels a bit hollow.
