I don't see whats new here - comparing global object values has always been used to identify browsers and versions. Same with looking for bugs/quirks in JS engines. New extension idea: adds random properties to window on each new page.

I believe the new stuff is the exhaustive approach ("5796 different properties between Firefox and Chrome"), which is a bit scary actually.
