Even for read-only use cases?
I've talked to _lots_ of folks who have nearly 100% IaC coverage, including folks who only expose read-only console access to the majority of their devs. But I haven't met anyone who has successfully managed to avoid logging in to the console during production incidents to debug things.
One feature we're looking at potentially adding is "Go To Definition", that lets you go from the AWS Console and jump directly to the Terraform code that produced that resource. Would that be useful to you?
