I don’t have any issue with that kind of technology, for what it’s worth. You’re only seeing how people use your site so you can figure out how you might tweak things, or understand what you need to do less of if you’re scaring people away.

There is a valid argument that this still presents a datapoint that can be tracked, but since the change is happening server-side, it is less useful than if you sent the same thing from your browser in every request, adding to your unique fingerprint (as with
Do-Not-Track, an abject failure of a standard4).
