At https://en.wikipedia.org/wiki/Template:DISPLAYTITLE#Instructions it says merely "Type {{DISPLAYTITLE: anywhere in the wikitext." MOS:ORDER also documents scenarios where DISPLAYTITLE must be before or after infoboxes. I am concerned that infoboxes are not banned from later sections of articles, so if we pull DISPLAYTITLE from the end/a near-end section of an article we could introduce a problem.

So if you are sure AWB is wrong to leave DISPLAYTITLE where it is at end of article, how will we establish that moving it will never introduce a problem?

@Rjwilmsi - Good point about DISPLAYTITLE sometimes needing to be below infoboxes. I'll mark this request as declined.
