If I'm not mistaken, in dark knight rises, wasn't Batman kind of rusty having not been active for 8 years? And as said before...it's Bane. He had not yet faced a physical challenge like that before. Also, let's not kid ourselves. The entire reason that sequence existed was to placate any fans who always wanted to see that scene from Knightfall. If Nolan wasn't aware of it, I'm sure someone made him aware of it during the scripting stage.
As for that scene during BvS, did we ever find out if that was a dream or a vision or...what exactly? Yes, I saw Darkseid's demon thingies so I know what it's hinting but it didn't make the scene more sensical OR instrumental to the film whatsoever.
