Ah, reading the bug report, it seems that the issue was not that they pack the address bits somewhere, but rather that they (a) allocated the spreadsheet data array statically and (b) had some performance issues with higher limits because the code was apparently not very smart about things like format changes to vast swaths of cells even if they are not being used for anything.

The new 2²⁰ limit was, not surprisingly, chosen to match the latest version of Excel. (Apparently, the abovementioned problems still prevent an integer-size limited value like 2³²−1.)
