I would do this in a first CL, without adding any code besides the new feature,
and the test for that feature.

Maybe should consider adding this feature to
https://cs.chromium.org/chromium/src/chrome/browser/android/chrome_feature_li...

so that we don't need a new bridge api for whether this feature is enabled.
