My opinion: Many Meta tools and processes seem like they were created by former Googlers that sought to recreate something they previously had at Google, during the Google->FB Exodus, but also changed aspects of the tool that were annoying or diverged from their needs. This is not a bad thing.

Since Bento doesn't appear to be usable by the public, aparallel version of this that people can get a feel for cross-tool integration would be Google's Colaboratory / Colab notebooks (https://colab.research.google.com/) that have many baked-in integrations driven by actual internal use (i.e. dogfooding).
