The NextAction date has arrived: 2018-12-21

govind@ I checked 73.0.3647.0 and didn't see any issue, the feature is in M71 but disabled by default, QA team already turned it on locally when they tested M71 and M72,    we tried to turned it on by finch for M72 Beta, for some reason, the feature wasn't turned on, so we decided to enabled it by default, in the meanwhile, we will find finch's issue. 

Approving merge to M72 branch 3626 based on comment #8.

Are you planning to revert this change (enabling by default) from M72  after Finch issue is resolved?

Pls merge your change to M72 branch 3626 ASAP. Thank you.

Re #9, No, it will not be reverted, if finch issue is fix, we could use it to disable the feature once something bad happen.

Ok, sounds good. Thank you.
