Describe the feature

Currently, the only way to enable termination protection on a CDK Stack is in the props passed to the Stack's constructor, e.g.:

const myStack = new MyStack(app, "MyStack", {
    terminationProtection: true,
    // ...
});

However, there is no way to set termination protection on an existing Stack instance. E.g., in the code above, if I then write myStack.terminationProtection = false, then I get the following compiler error:

Cannot assign to 'terminationProtection' because it is a read-only property.

I request that this property be writable.

Use Case

I'm trying to define an Aspect to enable termination protection on all of my production stacks, so that I don't accidentally forget to enable it in the CDK app. I was hoping to define this Aspect as follows, but instead I get the aforementioned compiler error.

export class ProdTerminationProtectionAspect implements IAspect {

    constructor(private readonly isProduction: boolean) { }

    public visit(construct: IConstruct): void {
        if (!this.isProduction || !Stack.isStack(construct))
            return;

        construct.terminationProtection = this.isProduction;    // ERROR
    }
}

Proposed Solution

No response

Other Information

Alternatively, you could take this as a feature request to add an "auto-termination-protection-enabling" Aspect to the CDK itself. 🙂
