LGTM. Would just like to discuss that one point.

Before merging this: what is the plan to ensure that the migration from the idfile to the statefile happens within 1 release cycle? How do we migrate?

The idFile is only removed in the last step (see user stories in Azure). So the code is not broken at any point.
When we prioritize this story, it should be very feasible to merge this in the next release.
Otherwise, we would have both the idFile and state file during the intermediate release.

Good to merge from my side.

Doc comments in this file need some work, but should probably be handled in AB#3426
