Interesting idea. I think this goes along with other places where we are 
unsound. Here, we err on the side of soundness. but, in general, we should have 
a configuration mechanism for this.  FWIW, the only reason we have 
uninitialized values at this point is recursive types. We also limit the depth 
of structs, but that should be removed given my recent patch to only model 
relevant fields. I have an idea for lazy initialization of values that I think 
could solve the recursion issue. Together, we could remove this concept of 
unmodeled values altogether from the framework.
