I didn't remove it, I 'moved' it later.  Otherwise the populate_sdk_base case is 
never run, when the image case has already been loaded.

So the flow goes from:

if image class:
   do work
   return

do other stuff

to

if image class:
   do work

if sdk class:
   do other work

if either image or sdk class:
   return

do other stuff

The behavior is the same for the image only class, the only new behavior is 
adding in the remap for the SDK only (or combined w/ the image) case.
