Comment:

 An alternative implementation I thought of would be to introspect the user
 model and see if it has a `last_login` field and avoid connecting the
 signal if not. I'm not sure it's feasible with
 `user_logged_in.connect(update_last_login)` at the module level since
 `get_user_model()` can't be called there, but maybe if the signal
 connecting happened in `AuthConfig.ready()` that could work?
