   I assume you mean `b.c=!1`
   
   It's not just `==`. You'd also need to do `bool1 = !!bool2` for every single assignment because you never know if bool2 was initialized.
   
   XML and JSON are two examples of cases where undefined produce undesired results. There's probably more.
   To me the "cost" is more the memory consumption than the cost in code, but cost in potential bugs outweighs both of those.
   
   I don't understand what you mean with backing variables, but that doesn't sound free either.
