Updating sitelinks on the repo (and thus language links on the client) should not require the respective wiki page to be re-parsed. Once language links coming from the repo are available in the ParserOutput separately from the links in the wikitext, we can update the effective rendering without re-parsing the page.
Crazy idea: background job to grab the parser-cache entry, update the language links, and push it back to cache if nothing else has changed. Might.... work. Or might be crazy. :)
