I still think Han should have held some resentment/distrust towards Lando in ROTJ for what transpired in TESB.

By "for what transpired in TESB" I guess you mean when Lando saved the lives of and entire population as well as our heroes from what would other wise been a bloodbath?
I think the writers understood that after Han heard the whole story, he'd understand Lando's situation and motivations and even be thankful that he did what he did.
I'd like to see that scene, but not one where Han acts like a dick to an old friend who saved everyone's life including his own.
