What if over successive unreverted edits of a page, sections of text that don't change start building 'longevity points' and users who post unreverted changes build up a similar sort of counter or user level. While edits to pages would still remain controlled by the existing rules, warnings could be sent when a low level user makes changes to long standing text. It would also be interesting to have two colorized versions of a page available- one which shows by color the amount of time text has stood unchanged (red is new, green or black is old), and another which shows the 'longevity rating' of the text (red is low, green or black is high). That system or something similar could help weed out bad edits without restricting user mobility.
