Looks like an interesting tool for infrastructure automation. It's all Python based which is an interesting departure from yaml files in that space. Could be a nice alternative to Ansible. I might take it out for a spin.

Keep things as simple as possible, they might turn out to be robust too.

Good piece on how to reduce uncertainty before something is built and ready to be in front of users. It starts with prototyping but goes all the way to feature flags and deployment

Python is making progress regarding portable binaries and it is welcome.

OK, definitely not something I'd advise by default. Still, if you're in the right situation that might be an option. The fact that they don't deploy in one go is definitely a factor here.
