If you want a real world scenario, here is one

Polymer starter kit

https://github.com/Polymer/polymer-starter-kit

- npm

- bower

- polymer-cli

Doing a polymer test requires downloading and installing Web Component Tester, which then requires:

- npm

- grunt

- gulp

- bower

https://github.com/Polymer/web-component-tester

Polymer is indeed ridiculous. But there's a reason it's not used that often.

My relatively standard project (using React) needs just Yarn and Webpack. It's got quite some dependencies, but I've never run into those being insufficient.
