"Really need"? Probably not. I suspect it's a matter of convenience:
If you have a reference to the cell, and it can provide the row/col,
you're done. Otherwise, you have to walk the tree to find the relevant
row that provides that information.
The same sort of quick access applies in the case of aria-setsize.
You're right that aria-setsize looks like a property of a list, not a
item within the list. But, again, the code avoids the step of walking
the tree to determine the relevant ancestor that holds the set-size
information if the item has that info at hand.
