If you have an object that forever owns a reference to

Even if there are such cases, it seems we're going to
have to be a lot more careful about identifying them.
It might be safer not to have any APIs that return
borrowed references, or at least name them in a way
that make it clear they're dangerous and only to be
used with extreme care.
Having things like PyDict_GetItem where the *normal*
version of the API returns a borrowed reference seems
like a footgun.
