Is there discussion about adding this as a public API? It would be very useful for pytorch datalaoders with nested data structures. You want them to live forever, and the reference counting wrecks copy-on-write havoc.

EDIT: I see a discussion here: [Exposing public APIs for immortal objects](https://discuss.python.org/t/exposing-public-apis-for-immortal-objects/64264)
