CDK is quite great. My only gripe I have with it: even though you can synthesize raw CloudFormation templates from a CDK project using `cdk synth`, you can't upload the artifacts without running `cdk deploy` (so you can't actually use the synthesized templates to deploy, because the artifacts aren't there). This is in contrast to SAM which does exactly this with the `sam package` command. Generates raw CloudFormation and uploads all assets to S3 in the right place.
