A lot of problems similar to your complaints exist for CloudFormation as well. Instead of complaining about the language warts, you’ll be forced to use an even more cumbersome set of primitives to access arrays and hashes, and the messages will only get less sensible as you look for either YAML whitespace errors or inevitably write a converter to avoid using JSON. CloudFormation limits like number of parameters and outputs start to be a real pain to scale to support a production environment beyond simple demo stacks, and Terraform has more issues scaling with team members concurrently trying to modify system state due to its less strict modularization / locking model. Infrastructure as code tooling is all very primitive compared to what we take for granted writing most other traditional software but it will take some time and maybe another generation to do it well.
