#possible_fake_root ⇒ Object

If the app/stacks/NAME has been removed in source code but stack still exist in the cloud. allow user to delete by materializing an empty stack with the backend.tf Note this does not seem to work for Terraform Cloud as terraform init doesnt seem to download the plugins required. SIt only works for s3, azurerm, and gcs backends. On TFC, you can delete the stack via the GUI though.

down - so user can delete stacks w/o needing to create an empty app/stacks/demo folder
null - for the terraspace summary command when there are zero stacks.
       Also useful for terraspace cloud list_workspaces
