I don't recall the last time I saw someone on a non-massive (>24") monitor use a browser in less than fullscreen width. That'll get you resolution, which sounds like yet another way to subdivide people viewing a website.

Or we could just discuss per-session tracking in which a user has an uncommon width remaining for all tabs

"screen.width" and "screen.height" will also get you the screen resolution without any need to estimate things based on where the window is positioned on the screen.

again, this is stuff that's been there since v1, and is table stakes for any sort of fingerprinting. it's just not useful enough to matter.

In a vacuum, you're absolutely right. But every dimension we allow users to be sub-divided along adds another potential fingerprinting point. This isn't the most important one; hell, it's barely an important one. It is simply the fact that it's another inch down the path of being able to identify every single visitor.

All that said: You're right. It's a QoL feature that's objectively helpful, and I am tilting at windmills. The current state of the web has left me dejected and morose, and I am disheartened by something that's not worth anyone's time - certainly neither of ours.
