This used to be used to enable DNT header and tracking query removal.

We removed DNT header because it only serves to increase entropy and
make users more trackable. Then we stopped checking this setting and
started doing tracking query removal always. (Follow-up will be to
remove this code altogether, once we enable Intelligent Tracking
Prevention.)

So now this setting is unused. I thought I had removed it already, but
apparently forgot to do so.
