Since one of the great values and security issues related to big data efforts is the ability to derive behavior and other data, there definitely need to be policies.
On the other hand, not all data is created equally, so flexibility and a strategic context management approach needs to be developed. Since much of the more critical data may not be in traditional IT systems, IT organizations are going to have to listen, influence and justify any policies that span the corporate portfolio.
Remember that it is the business that evaluates the true value of the context generated by the data, not the IT organization.
I would actually change the question around a bit. Rather than asking if the "experience universe" gets in the way. I'd look for what elements of that universe remain true and what new elements need mental investment in order for their relevance to expand.
Nearly all experience may be useful, it just might be in a different way than the experience was consumed in the past. One thing everyone likely agrees upon is the days of the 'back office' CIO are in decline and business enablement is key.
