This has been mentioned recently in the other forum:

You can write a library for this. Also I wouldn't call it an alternative for reference counting as you can still attempt to use objects after freeing them. It just aborts rather than cause UB. By the way that article refers to the "generational indices" pattern for which there are already multiple libraries. It is also used in for example Bevy's ECS for entity id's.
