For consistency, we should probably add the flag on Android as well.

But for now, it won't do anything on Android (right?)
Can you create a downstream CL to honor the flag an Android as well, or should I
look into it?

That code is upstreamed now! :) The logic is in Java code though. If you want to
implement that, go ahead, if not, I can do it as well.

Right, awesome :)
Done!
