I can explain why that I don't think a blanket rule like that wouldn't work for my family.
We are two parents and a child who has used
DAS. Child is 11, so as I understand it, Disney feels that is old enough to wait in a queue alone and ride alone. In your example, Rider Swap would be our accommodation.
For a normal ride, one parent waits with child while other parent waits in line. After ride, first parent and child ride. Got it, that's fair, if not a great family vacation.
However, specifically for my family, one parent will not ride any "thrill" rides, defined fairly loosely. Anything with a real drop is out, from Barnstormer and Slinky and up. Trackless or simulators like Rise and FOP are OK.
So for these rides where we have 1 parent who will ride, 1 who will not and child with accommodation, we have a few options -
- Riding parent waits standby, child uses rider swap. This doesn't seem like much of a solution - just because Disney feels 7 years old is old enough, we don't feel that our child with a disability should be waiting on a line alone.
- Non-riding parent waits standby but uses the chicken exit, then riding parent and child ride. This is just silly.
- We skip this ride.
This may very well be the accommodation offered, and if so, I would at least explain the above. Perhaps Disney IT is working on a more limited or targeted system. If not and this was the only accommodation, we would likely skip (or drop rope) as much of these rides as possible, only if rope drop is possible on those days based on child.
