Sorry maybe my last reply was a little harsh now I understand it isn't a priority IaC under the hood anymore.

I still have major reservations around dropping IaC and just working on a simulation of what is deployed, I don't see how this can work for more complex deployments such as multiple region/AZ deployments, blue/green deployments, cell based deployments etc etc. Seems like dropping IaC would only work for very simple environments.
