Since the number of Electron apps probably isn't going to decline anytime soon, I think I can save you some work. I could write you a little application that scans HN a few times every day and if it finds a discussion about an Electron-based project it will post a comment letting everybody know that you won't be installing it because it uses Electron.
If you are interested, let me know. I can knock it out in a day or so and it will work on any platform you use because it's based on Electron.
