On the list above, I agree with 1-4, and am more cautious towards 5., 6. Whether or not it is a deal killer people need to judge by themselves. Being aware of a problem certainly helps with a proper individual assessment.
To 5. and 6., we don't know what causes the banding as of today. But we do know that we can work around this in post (thanks Warren!).
Concerning the deal killer, I'm not quite sure. This back does also a lot of things right. It's a joy to use on the old Hasselblad cameras. It does work as intended on longer lenses. Usability is super. It enables the use of X lenses. So there is still a lot on the plus side of the equation. But yeah, how the factors are weighed, that's completely up to each individual.
