Thank you for opening this pull request. I think the feature is a good
idea, but I would like to approach it a bit broader:
- On state restore, this should prefer the old state location, agreed
- If no such location exists, it should still try to co-locate by input.
Especially for the batch execution, that is quite important.
Also, this would need some tests.
I'll add some more detailed comments to the issue soon...
