No matter how you like to participate in developer communities, Pulumi wants to meet you there. If you want to meet other Pulumi users to share use-cases and best practices, contribute code or documentation, see us at an event, or just tell a story about something cool you did with Pulumi, you are part of our community.

Pulumi Community

Given an AWS account is a flat namespace, you can have multiple Pulumi stacks each setting up part of a deployment. Destroying a single stack should only destroy what is managed by that stack. So this is not something that Pulumi will offer.
You could use the AWS SDK libraries yourself to write an automation that uses `List…` calls to enumerate what is on the account, and then perform `Delete…` calls to remove these resources.

I think this is more of a job for a tool like <https://github.com/gruntwork-io/cloud-nuke> rather than Pulumi.
