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.
It works great. If you think of it as 'dropping all the reasons we chose IaC', then yes - that's obviously dumb. If you think of it as 'getting all those benefits, plus faster feedback loops, AI agents, and an easier programming model' then.. not so much.
