New description:
Currently, writing a new authentication backend requires quite some
boilerplate e.g. `has_perm()` can be derived from `get_all_permissions()`
which in turn can be derived from `get_user_permissions()` and
`get_group_permissions()`. Additionally, `authenticate()` and `get_user()`
should always return `None` for backends that only handle permissions.
Also note that `get_all_permissions()` and `get_group_permissions()` exist
on the User model, but `get_user_permissions()` does not. I think this is
confusing for backend authors.
