By edchat:

It looks likes the original drop of _DataBindingMixin had something like this at the top of _updateChildBindings.

var binding = this.get("binding");
if(binding){
var val = binding.get("value");
if(val != null){
this.set("value",val);
}
: : :
The null check in the code above is what was removed when the null check was added.

I successfully ran all of the tests with the val != null commented out in _updateBinding, so I would think we could remove the check.
//if(val != null){
this.set("value", val);
//}
