When a page contains a invalid displaytitle ({{DISPLAYTITLE:invalid}}), please report that with a system message on that page. It is hard to find all this cases. The title can be invalid after page move and than nobody repair it. When having a message, it is possible to add a category and find the pages.
Please also add the message when there are two or more displaytitle on the page, but one is invalid.
Thanks.

Change 158098 had a related patch set uploaded by Jackmcbarn:
Warn when a restricted displaytitle is ignored
My patchset was merged. I'm not sure why gerritbot didn't post here about it.
That was because commit message referred to the old bugzilla ticket number btw.
T135949: Disruptive: Display title ... was ignored since it is not equivalent to the page's actual title proposed adding a tracking category and also modifying it's behavior to not show on the actual page's output.
