The idea is to add some space editable only by sysops (or some other group).
This space would be merged with the article so it would be shown on top of the
article. This could contain some messages about the article that would have to
be change by some selected group of users. There would also be some triggers
that would fill this field automatically:

• on new-page fill with "{{warn newpage}}" (text changeable trough MediaWiki:)
• on change by IP fill with "{{warn IP change}}"
• on change by some-group fill with "{{warn some-group change}}"

...?

Of course communities could decide to blank the text to be inserted on some
events (through MediaWiki namespace). Note that this functionality would also
assure that when some important template or some administrative category is
inserted it will stay there, so no backlogs or stuff like would be needed.

Technically it wouldn't have to be long so it could be a simple varchar(255)
field or even smaller (though not too short so long category names could be
inserted). Adding this restriction would also stop some users from moving the
real article's content to this field.
