Comment:
As far as I'm aware, fields are quite specific, in a real life they don't
live without models. Field's hash should change when it's assigned to a
model, comparing `creation_counter` is not enough. We shouldn't consider
the same field instance assigned to a different models as equal. IMO the
current behavior is expected, we don't want to reintroduce an issue fixed
in 502e75f9ed5476ffe8229109acf0c23999d4b533.
