One more question regarding retainOnDelete: https://www.pulumi.com/docs/intro/concepts/resources/options/retainondelete/:

The default is to inherit this value from the parent resource

Is this meant to imply that setting the option to true on an existing resource should cause the option to be set to true on its children, or is it something more nuanced like “those children won’t be deleted because the parent won’t be deleted, even if

pulumi preview

labels them

delete

rather than

delete[retain]

“? (As far as I can tell, neither of these is true—children seem to be “really” deleted even if their parent resource has the option set.)

You are right. We need to revise this for Pulumi v4 https://github.com/pulumi/pulumi/issues/7346#issuecomment-1542616529
