We might take another look, but back when we launched an internal platform, it was literally impossible to import manually created resources into CloudFormation. Terraform was the only game in town. I also keep hearing about long delays in CF supporting new features; the TF provider is usually well maintained. I wish either of them had a more graceful plugin story, though.
