First, the better question is what advantage is there in building such limit=
ing present day limitations into the future?
Second, the answer is facilitate a broad range of automated hierarchical top=
ologies allowing for both breadth and depth of prefix distribution among par=
titions within the home environment. I admit we have not even begun to scrat=
ch the surface of how, where, or why these topologies may evolve, but I can s=
ee that due to the tendency for software to be developed to the lowest commo=
n denominator, if we make said denominator too low, we will forever blockade=
the opportunities for such innovations to see the light of day.=20
