From #76:

• Add stateful: boolean to cdk.IResource
• Refactor RemovalPolicy to an enum-like and move apply to there
• Consider how/if we should model statefulness in L1 considering AWS Resource Model #73
• Implement and apply rule awslint:state-annotation: All resource classes should be marked with "@stateful" or "@stateless"
• Implement and apply rule awslint:state-removal-policy-prop: All stateful resource should have a "removalPolicy" prop
• Implement and apply rule awslint:state-stateful-property: All resources should have a "stateful" property returns true/false

Already exists in a basic form. Unclear what more is proposed.

Marking this RFCs as stale since there has been little recent activity and it is not currently close to getting accepted as-is. We appreciate the effort that has gone into this proposal. Marking an RFCs as stale is not a one-way door. If you have made substantial changes to the proposal, please open a new issue/RFC. You might also consider raising a PR to aws/aws-cdk directly or self-publishing to Construct Hub.
