So why is Terraform so popular instead of your tool? :)

Both approaches have tradeoffs, and what you've mentioned are clearly advantages of the full-PL config style. The problem with a full-blown programming language, though, is that the flexibility makes it more difficult to reason about effects without actually running the code. If you're just using it to generate a declarative data model that then gets applied, you're still doing fully declarative management, just with extra steps.

It's not _necessarily_ a good thing to have something like if conditionals in a provisioning system either - the goal with these systems is usually to reduce uncertainty about outcomes, not multiply the # of branches you need to reason about. Ultimately I agree Terraform has issues with restrictions of HCL, but I don't think I'd say choosing a programming language instead of a purely declarative style is a no-brainer.
