I think the "Redux" footage would be better served as traditional deleted scenes.
I'm interested to view those scenes but they ruin the "ANow" experience for me, so I'd rather just be able to see them solo, not stuck in the middle of the movie...
This goes to the extreme in the "Oz" 4K thread. There people complain it might not have Atmos and also complain it might not have the original mono! <_<
