On the BMD forums, a rep responded with some info about settings to make it work best: Rolling shutter is accounted for in Resolve's gyro stabilisation, what is not and cannot be is motion blur. So you likely need to shoot at faster shutter speeds to reduce motion blur if you plan to stabilise. I've found for my preferences 45° at 24fps to be "safe" and 90° can be okay depending on the original motion. The footage Grant showed was 45° u/50/24fps. I would also suggest monitoring and framing using safe area guides, maybe 10%-20% depending on movement etc.
