I've had Terraform break several times when my AWS STS token expired half way through a deployment. When that happens I ended up having to manually delete all the created resources because the Terraform state was corrupted to the point I couldn't reapply to create the remains resources but also couldn't delete the existing resource with Terraform. That said, I agree in general that this wouldn't be the main reason to use the Cluster API over Terraform.
