Thanks for the update. Regarding migration, I think the format that we
write to the savepoint must be the same between the two `ListState`
implementations.
@StefanRRichter could you please have a look at this? And also
@StephanEwen, I think you did a similar PoC implementation of this a while back.
@je-ik It would make sense to change the title of the PR to reflect what
this does now better.---
