Hello

Would it make sense to also include similar methods for Rc? And possibly similar ones to both Weaks? It would be in part for the sake of completeness, but I do some manipulation like this in the arc-swap crate and if this would become the „official“ way, it would be nice to be supported on all the related types.

I think that's a great idea, and we should file follow-up issues to implement those.
