jsii assemblies contain redundant dependency information

[rix0rrr]

Looking at the start of the dependency section of the @aws-cdk/app-delivery assembly, it looks like this:

  "dependencies": {
    "@aws-cdk/aws-cloudformation": {
      "dependencies": {
        "@aws-cdk/aws-iam": {
          "dependencies": {
            "@aws-cdk/cdk": {
              "dependencies": {
                "@aws-cdk/cx-api": {
                  "peer": true,
                  "targets": {
                    "dotnet": {
                      "assemblyOriginatorKeyFile": "../../key.snk",
                      "namespace": "Amazon.CDK.CXAPI",
                      "packageId": "Amazon.CDK.CXAPI",
                      "signAssembly": true
                    },
                    "java": {
                      "maven": {
                        "artifactId": "cdk-cx-api",
                        "groupId": "software.amazon.awscdk"
                      },
                      "package": "software.amazon.awscdk.cxapi"
                    },
                    "js": {
                      "npm": "@aws-cdk/cx-api"
                    },
                    "python": {
                      "distName": "aws-cdk.cx-api",
                      "module": "aws_cdk.cx_api"
                    }
                  },
                  "version": "0.28.0"
                }
              },
              "peer": true,
              "targets": {
                "dotnet": {
                  "assemblyOriginatorKeyFile": "../../key.snk",
                  "namespace": "Amazon.CDK",
                  "packageId": "Amazon.CDK",
                  "signAssembly": true

• Why does it contain transitive dependencies?
• Why do the dependencies have information on the targets and their build instructions (../../key.snk???) in there?

For funzies... in a package with highly complex dependencies such as @aws-cdk/app-delivery, removing the dependencies node from the assembly reduces the file size from

8.2 MB

to

18 kB (!!!!)
