> Spark Connect introduced the concept of resource isolation (via ArtifactManager which has seen been ported to classic Spark) and thus, jars/pyfiles/artifacts added to each session are isolated from other sessions.
> A slight rough edge is that if a user wishes to fork the state of a session but maintain indepence, the only possible way is to create a new session and reupload/reinit all base jars/artifacts/pyfiles etc.
> Support for cloning through the API helps address the rough edge while maintaining all the benefits of session resource isolation.
