Comment (by timgraham):
The description of that PR gives an example of the behavior you describe:
One can also do the following after the patch:
{{{
obj = MyModel.objects.first()
del obj.field
obj.field # <- Loads the field from DB
}}}
so I'd say that yes, that's what Anssi intended. Whether or not there's
justification to change the behavior is another question, although the old
behavior seems untested and undocumented so backwards-compatibility likely
isn't extremely critical.
Could you explain your use case? Are there any ways to achieve it after
the change?
