I'm not familiar with Buildbot, but the benefit you're describing I think exists in Concourse as well. When you define a task you can just point it to a script to run. This can be a script written in a higher level language if you'd like.

This is similar to how some Concourse Resources are implemented with Shell[1] scripts, and some in Go[2]. -- 1. https://github.com/concourse/git-resource 2. https://github.com/concourse/tracker-resource
