As a tenant auditor it would be useful to be able to track some additional model events such as changes in model mode or when a model was created/deleted.
One such scenario is if a model is accidently deleted, a tenant auditor would be able to see when and who deleted said model without relying on Anaplan support.
Another scenario is if a model has lost ALM sync compatibility, this would allow a TA to see if the model was ever taken out of deployed mode without relying on Anaplan support.
