@peternied maybe I missed it, but could you add a really clear explanation about the interaction between Views and roles? I think we want to make it really clear that we still use the normal permission system behind the scenes otherwise it may seem like Views can skip the normal check or are an alternative permission system.

I have documented the feature as it is, as it changes I'll need to revise this PR.

There is no change or loosening to any permissions - you'll need both index permissions as normal in addition to cluster permissions that allow calling the different view APIs

I'm going to close this out - until there is a clear delivery data associated with this feature it doesn't make sense to clog up the PR queue. I'll reopen if it becomes relevant in the future.
