CDK is an abstraction over CloudFormation, which is an inconsistent (in how it deals with similar things at the next level down) abstraction over the individual APIs of AWS services, which themselves are not particularly consistent to start with.

Well, lots are, because it's less tedious than raw CloudFormation or thin improvements over it like the Serverless transform, and AFAICT most of the inconsistency is from the underlying CF behavior, so isn't avoided by cutting out the additional layer.
