I propose another workaround alternative that doesn't exist yet. A "multi-browser" which lets you browse and visually diff the web from different points of view. See the web from deep china, europe, Kansas City, San Francisco, Chrome, Firefox, daytime and nighttime, incognito, logged-in, etc all at once (modulo some time spreading for opsec or something) so we can get back to peace and what matters: booking a bloody hotel room or reading a magazine article without making a project of it.
