------------------------------------------
Do you have an idea for FLINK-23252 already? Do you know when will you perform
the unwrapping there? It might influence the choice here. What do you think?
Personally, I don't have a preference between the two options suggested in the
ticket. I trust your judgement here. IMO, would be good to have a unified story
with FLINK-23252.

> If we restore from checkpoint with changelog state-backend enabled in
> snapshot CLAIM mode, the restored checkpoint would be discarded on subsume.
> This invalidates newer/active checkpoints because their materialized part is
> discarded (for incremental wrapped checkpoints, their private state is
> discarded). This bug is like FLINK-25478.
