Yes, but have you written another program like that in the last twenty years?
That is an exceptional case, a program that requires what amounts to an array of
more than 2^32 elements, and a file that can be greater than 2^32 bytes in size.

Once the tables are built, it is convenient to use 64-bit values to access the
data, but a 64-bit processor is no great win there.
