Let's rename the old dataset last element to the clone name. For example:

source/dataset@a @b @c [rollback to @b] @d

Old backup: target/dataset @a @b @c [ROTATE] target/dataset:c [contains snapshots a, b, c] target/dataset@b @d

This is working in branch feature-clone-rotate.

This works after a rollback event, after a source rename/clone event, or after a target diversion for any reason.
