I think it's designed to be a more matinable version of Electron, which bundles Chrome with every app that uses it. I have at least 3 or 4 copies of Chromium sitting around on my desktop at home because I use a few Electron apps.
One time, there was some BeagleBone tutorial that recommended using a Windows version of dd that is implemented as an Electron app. It was 200MB. For dd. Not great. At least this uses the Chrome you already have installed.
