DRF validate on serialization read_only.py

# BooleanField.FALSE_VALUES.add(None) # does not help
class S(Serializer):
bf = BooleanField(required=False, read_only=True)
class example:
bf = None # I expect it to become **False**
s = S(instance=example)
assert s.data['bf'] == False # Fails, because {'bf': None}
