Any updates/likely merge time on , or at least a worked example of how to add AWS::CloudFormation::Init to an autoscaling.AutoScalingGroup?

The following template shows that it should be added to the AWS::AutoScaling::LaunchConfiguration in the CloudFormation:

I see that makes reference to being able to find/modify children since 0.10.0. Following the syntax there… it looks like the following should work for us…:

// Ref:
// Ref:
const asgLaunchConfig = asg.findChild('LaunchConfig') as autoscaling.cloudformation.LaunchConfigurationResource;
asgLaunchConfig.addOverride("Metadata", {
    "AWS::CloudFormation::Init": {
        "FOO": "BAR",

Running cdk synth, I get the following, which implies it is working as expected:

  Type: 'AWS::AutoScaling::LaunchConfiguration'
          FOO: BAR
