I can't think of a project of any size that terraform would be excessive for.

Agree, if you're introducing it to a new team and don't have time to teach the tooling that could be problematic.

But being somewhat familiar with Terraform I would use it to launch a single EC2 instance. Because it's about as fast to do that as it would be for me to use the AWS Console.

It's not that I think Terraform is needed for that small of a project, it's that it adds no cost even for tiny projects.

The original comment suggested that Terraform was being introduced at the wrong time.

You are right that size is not the best measure of suitability.
