I think I've taken this as far as I can, the difficult bit to wrap my head around is the deleting steps!
The next questions I think are:

1. what shape should the JSON file take
2. should existing functions/commands be leveraged to do the actual cleanup
3. should the JSON file be retained for subsequent cleanups if needed (I'm already keeping the SubscriberPackageVersionId for this purpose)
