I think it would make sense for diff and deployto indicate termination protection changes of stacks

I noticed that when you are changing termination protection of a stack, neither diff nor deploy will make any indication of this change.
Wouldn't it be reasonable to have diff output whether termination protection has been enabled or disables, and have deploy output that this action was in fact made.

On a separate note: I would love to have a feature flag to enable/disable termination protection for all stacks. Currently I'm using an aspect that will set termination protection on each stack.

Setting terminationProtection to true (default false):

const app = new cdk.App();

new CdktestStack(app, 'CdktestStack', {
  env: { account: process.env.CDK_DEFAULT_ACCOUNT, region: process.env.CDK_DEFAULT_REGION },
  terminationProtection: true
});

doesn't report the change when running cdk diff:

Stack CdktestStack
Parameters
[+] Parameter BootstrapVersion BootstrapVersion: {"Type":"AWS::SSM::Parameter::Value<String>","Default":"/cdk-bootstrap/hnb659fds/version","Description":"Version of the CDK Bootstrap resources in this environment, automatically retrieved from SSM Parameter Store. [cdk:skip]"}


✨  Number of stacks with differences: 1

Appears to be useful feature to report change in terminationProtection for a stack.
