A lot would depend on the details. While $40-$80 per person per night sounds like a lot, when you start adding tickets and food (as described above), it's really not.
DDP by itself, in non-peak seasons costs ~$51 per adult per night. A 10 day base ticket is $318 per adult (so, ~$32 per day). This combined is already ~$82 per night and the DDP is quite limited as far as the credit structure is concerned. Certainly not proper for an "All-Inclusive" feel.
For a better comparison, you'd look at the platinum plan for inclusivity, which sits in the ~$200 per person per night range. And even this is a bit limited as you do not get unlimited food and drinks. I'm not sure about the shows and tours here either. I know they're included, but I don't know if there are allotments or what.
I don't see the $40-$80 price tag (even theoretical) as anywhere near feasible to craft a true all-inclusive type of plan when they already have something close to it that's over twice that price and is still more limited than a real all-inclusive type of deal.
Now, if this were a $40-$80 price tag on TOP of tickets, resort, AND at least DxDDP, it may be a bit more feasible. (Too rich for my blood, but feasible from a Disney perspective). Still don't think it would work due to the already existing premium and platinum plans being roughly more than that though.
Of course, survey questions are survey questions and are not necessarily portents of things to come
