While techniques like these are undoubtedly handy for analytics, advertising, affiliates, etc. in my opinion they go against the actual purpose of a URL. Removing such suffixes makes my URLs cleaner and defeats the purpose of the tracking mechanism, a practice which hopefully some day will be so commonplace that this kind of tracking is abandoned. (And there are tools that automate it, so it could some day become a tracking blackhole the way adblock is, if such a feature is ever integrated into a popular piece of software.)
