i can understand irritation with banding, but in terms of dynamic range being behind the curve, i feel like we're in an emperor's new clothes sort of situation.
i'm willing to bet if you took a random sampling for thousands of photos taken with cameras/sensors from canon, nikon, or sony, you nor any of your clients would be able to discern which cameras took which photos based on dynamic range variations. there are plenty of things that could use updating, but i don't feel as though this is something that anyone seriously considers a dealbreaker unless they're nitpicking test charts.
You run into the problem as soon as you try to push the shadows.
Normally, you expose for the highlights, so as to avoid blowing them out.
If your camera has sufficient dynamic range, you can then lift the shadows to expose detail. If it does not, lifting the shadows will only expose blotchy noise.
You won't notice any problems looking at photos. But you'll notice them as soon as you try to process said high-dynamic-range photos.
