This paves the way for a contiguous descriptor array. A contiguous descriptor array has the benefit that we can make strong assertions about whether an address is a valid descriptor or not. The other benefit is that future generations of I/OAT hardware will require a contiguous descriptor array anyway. The downside is that after system boot, big chunks of contiguous memory is much harder to find. So dynamic scaling after boot is basically impossible.
