I see it as R07 just pulling his troll despair card that he likes to use. The Gou arc is meant to be similar to the original where it's about people working together to solve a problem. It's about taking the lessons from the original series and applying them to get a good ending. Then of course because it's WTC it gets turned on its head and the whole thing is shown to always be pointless with the new rules.
It still stands on its own in the previous work, but as a sequel it's meant to dump on the previous lessons so that you can be put in despair.
