Yes, it is amusing.  But, that bug is for accerciser, not oocalc 
itself.  So, ...

If the spreadsheet is large enough, I presume, perhaps incorrectly, that 
oocalc does not load all of the cells into memory from the hard drive 
until the user scrolls to them.  If that is the case, what exists in 
ATK/AT-SPI for the subset of the cells that are loaded? Put another way, 
what does oocalc expose through ATK for the partial load, specifically, 
the number of cells and the position in the set?

These questions are a starting point regarding how to modify the ATK API 
as you suggest -- if oocalc is doing something reasonable, perhaps that 
can inform the improvements.
