I believe that kernel interface is not really meant to be operated on the level that's directly accessible by the end user. The food chain is a bit different. The human user interacts with userlevel apps, not with kernel API directly. The userlevel apps interact in turn with the kernel APIs, either directly or via the layers of libraries. The abstrations that's presented to the human use are not necessarily 1:1 reflection of the kernel APIs. For example, you could program your novel way of permissions as a new file manager application that actually uses existing posix permissions underneath. Your file manager could check with userlevel-stored policies to implement the permissions that you describe, without any changes in existing kernel and existing filesystems. To expect that posix-compliant kernel will drop its posix complicance for temporary experiment sounds a bit far-fetched to me. But the door for all kinds of experiments is widely open in the userlevel.
