Review comment:
Maybe instead of adding `originalCopy` here we could simply change this
method to return the reschedule delay only. I think that would fit better in
the current flow. Then we can use the `ReconciliationUtils.toUpdateControl` in
the controller
What do you think?

Why did you add the serialVersionUIDs?

Review comment:
I think this is a valid safeguard but I think the error should be
something like:
```
Detected spec change after reconcile, this probably indicates a bug.
```
