While I agree that a fully automated system is something best left to researchers rather than Mediawiki engineers, some degree of automation is indeed possible. For very simple examples, it is trivial to detect changes that make no difference, and automatically approve those. Things such as whitespace changes, changes to comments, changes to escaped i18n strings in a separate file / page, and so forth. In fact, there is an existing library for i18n in mediawiki, but that requires an extra ajax call.

So there is still room for improvements even without full automation.
