Personally, I feel that as individual articles mature, imposing greater control over the content development process is a natural and in many cases neccesary part of Wikipedia's evolution as we move towards greater quality. There are many high profile, well-developed articles where well over 50% of the recent edits are consumed by vandalism and combatting vandalism, and that is a wasteful use of people's time and resources.
Hear hear. See [[List of countries]] for an example!
