Merely as the technical answer to your question, not as advocacy: CFN has custom providers [0] and they've started publishing quite a few implementations on GH (but I haven't tried them to know if they're for real): e.g. https://github.com/aws-cloudformation/aws-cloudformation-res...

As far as I know, it is possible to bridge terraform providers into a CFN stack using that mechanism, similar to how Pulumi works
