When introduced in bca5327b21eb2e3ee18292cbe532d6d0071201d8,
GenericForeignKey was created as its own class. Since then, it has grown
to resemble a field, particularly in
fb48eb05816b1ac87d58696cdfe48be18c901f16.
GenericForeignKey *not* being a `Field` leads to several issues:
1. It is added as a “field” and returned by `Model._meta.get_fields()`, a
type confusion [https://github.com/typeddjango/django-
stubs/blob/5a8e7b3855ea6f7be2b2ab928d02eff9a748d917/django-
stubs/db/models/options.pyi#L122-L124 reflected in django-stubs].
2. It duplicates code, such as `_check_field_name()`.
3. It misses methods like `__repr__()`.
I think we should make it a subclass of `Field`.
