We have displaytitle magic word. However that affects the display only when viewing that particular page. This value is stored in page_props table. The idea is to integrate this value into the linkbatch, so that we can display correct* titles everywhere * There are multiple uses for this, like marking title direction, working around the limitations of title names in mediawiki, showing a title that is different from the actual page name (translate extension)...
This will need integration with various parts of core. Title, LinkBatch and LinkCache come to mind.
