Currently, the HTTP Content-Language header returns the site's fixed content language. For a multilingual site like wikidata.org, this is useless at best, of not misleading. At least on pages showing data items, the user interface language should be returned in the Content-Language header, to indicate the language actually used to render the page. This would also help to solve the caching issues described in bug 41451.
[replacing wikidata keyword by adding CC - see bug 56417]
