Electron has nothing to do with ChromeOS. In fact ChromeOS could not run Electron apps until the very recent "Linux app support" that's still not available on all devices AFAIK. (Or developer mode hacks + awkward ways of exposing GUI to Chrome that don't support GPU acceleration.)
Another one that didn't get the message that shipping Chrome as application runtime, with Chrome specific APIs, not available as Web standards, is hardly any different than turning the Web into ChromeOS.
Your post above reads like an incorrect factual statement, not vague message.
Either way, Electron's APIs for using native parts of the app from the web part are purely Electron's and DO NOT exist in other Chromium based products.
