When the extension is registered with the [Runtime Extensions API](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-extensions-api.html#runtimes-extensions-api-reg), that's the name that the extension will be registered with. If you want to register the extension with a different name, you only have to rename this binary file and deploy it with the new name.
