except for globably admin as not overridable and core.manage which is just an admin view a list of items only permission, there is no inherent ranking of permissions.  Some would say the right to edit.state is the most important because that changes what site vistors see.  Some would say delete because that changes things pernently. And so on.  I would not impose a ranking on either developers or webmasters since you don't know what makes sense for them and the whole system is designed to explicity NOT reproduce the kind of "ranking" we had in 1.0 and 1.5. in favor of orthogonal permssions.

Also, how are you thinking about situations in which developers are not using recursion/permission inheritance?
