Exploring Dagger: Building a CI/CD Pipeline for IaC

With all respect to dagger tool itself, I am still not convinced by this post in what dagger could give me for IaC?

1. If I need to run things locally I can use polumi cli

2. Dagger case in this post is just a wrapper around polumi commands, which takes a lot of coding just because golang is quite verbose language by itself, so I am not sure what benefits are ?
