Sorry, I hadn't yet done the verification step after proposed. Here is the log for a kinetic LXD which installs anacron and then updates it to the version in -proposed ((2.3-33ubuntu2) over (2.3-33ubuntu1)).

As can be seen, the service and timer are enabled both before and after the upgrade. We can also see that the work-around I added is triggered and points out that the service and timer have been disabled until the work-around kicks in.
