There are far more robust methods of fingerprinting to spy on users anyway (adding up all the details of screen size, available fonts, language, os, etc, etc), so I don't think removing the user agent would have much impact in reducing fingerprinting alone. It's also useful as a quick and simple way to check the type of device, os, or browser the user is on and serve the correct content (download link for one's OS) or block troublesome clients (broken bots)
not if you just simply turn off javascript.
I bet you can detect window size with css media queries and invisible “background-url” values for rendered items.
I don’t know if “display: none” prevents loading of background-url targets though.
Then browsers should just download ALL background-url images beforehand
