Except that google already told that they will not keep V2 for enterprises..

enterprises have a 6 months extension compared to the rest of people, actually anyone can enable a policy that re-enable V2 but google said that it will maintain that only for additional 6 months..

After that they will remove V2 entirely even from enterprises..

i doubt that google will keep the code around to support V2 for long after that.. Browsers that want to keep it will have to maintain the code themselves and deal with any problems and costs that it causes..
