I guess we'll find out in a few weeks when testing starts. My guess is that it'll be hidden deep in about:config somewhere.

Given Google's other tracking practices (X-Client-Data and leaky modern APIs like AudioContext), very unlikely.

X-Client-Data cannot be disabled (it's hard-coded) and ships telemetry to DoubleClick without disclosure.

Google Chrome is the DoubleClick browser. Why else would DoubleClick be hardcoded into the source as a place to send telemetry?
