Hi Amir --
Because VE is not widely rolled out and is controversial, we haven't spent a lot of time studying it after the initial rollout in 2013. AFAIK, that team is working on performance and functionality issues and I haven't heard anything about additional rollouts. Until we have a plan for this, I don't think we're going to spend a lot of time on VE studies.
I'd reach out to James F & co to get more information on their current focus on performance; certainly we'll continue to work with that team when the roadmap is clear.
