It's an improvement but for numbers around 10^10,000,000 you still need a table with O(10^5,000,000) entries ... not very practical when computers have not much more than 10^12 table entries to play with.
I'm afraid lots of people - including many with mathematical backgrounds - simply don't have much idea about the vastness of the numbers we're actively engaged in testing.
