The discussions about the open of rollback and patrol right are in progress at Chinese Wikipedia (zh.wikipedia.org). Some suggested that we can have two ways to grant right to the qualified users. One is auto-promote (by system), and one is by hand (by admin). That's mean two requirements are needed. The requirement for auto-promotion is higher, and if user met this requirement, he must be promoted by system. Before that, if users met another requirement, he can make an application, and admin can consider whether or not. I would like to know that, is this possible to run out practically?
