I would like that a system message would be introduced in mediawiki.
A system message that will be shown if the page is protected (not in the edit page, in the page itself)
pointing out that that page is protected (pointing out event to the ones who are allowed to edit that page anyway. This is aometime usefull to avoid missunderstandigs).
This can be achived now with a template included in the page, but it's tricky expecially if an automatical protection expiry is set up.
And, off course, similar message for page that are semiprotected, move-protected and so on.
These system messages should be translated in different languages and customizibile as usual.
