The only downfall to knowing that snake was improperly cared for and probably resulted in stunted growth is accepting the fact that in the long run, it will most likley have a huge impact on the length of the snakes life......most likely shortening it considerably, at least from everything i've read. I may be completely wrong, but i thought mal-nutrition in large boids was worse to the lifespan than the known problems with power-feeding shortening their lives.

If anyone else is more knowledgable on the care of previously malnourished/poorely cared for snakes, i'd love to hear them chime in. I'd guess that Rusty_Reptiles on here probably would have some good insight for this topic since i believe he deals with rescued animals on daily basis(at least i think thats what i've read, but if i'm wrong, please forgive me)

p.s.
for a good size comparison, my female(although she comes from a rather large line of females) was born 6/11/04, and is almost 3ft(probably more like 32-33inches...but i rounded up) and hasn't been powerfed at all. But her mother is a 10' female - and her father is a rather large adult as well.
