WHen can the CFG element invalid? Where is it coming from?
My argument is that the CFG element should be always valid, and if it's not
then my gut feeling is that that is because the CFG element is uninitialized.
And I'm dreading uninitialized values because they are really hard to track
down, and this is why I'm pushing back against this change to much just to be
on the safe side.
