I'm having a play with .NET 5.0 RC1 and C# 9.0... I think the improved target typing will help reduce ceremony:

var cluster = new Cluster($"{prefix}-cluster",
    new ClusterArgs
    {
        RoleArn = clusterRole.Arn,
        Version = config.KubeVersion,
        VpcConfig = new ClusterVpcConfigArgs { SubnetIds = subnetIds }
    },
    new CustomResourceOptions { DependsOn = clusterPolicies });

becomes:

var cluster = new Cluster($"{prefix}-cluster",
    new()
    {
        RoleArn = clusterRole.Arn,
        Version = config.KubeVersion,
        VpcConfig = new ClusterVpcConfigArgs { SubnetIds = subnetIds }
    },
    new() { DependsOn = clusterPolicies });

But there is a problem that

Input<T>

types don't play nice. For example, trying to remove

ClusterVpcConfigArgs

above causes a compiler error:
