As of today (30 November), at least on English Wikipedia, links to articles that fall below an individual's "stub link" preference length are not appearing in the rendered article text. Example: set stub link length to 250, and search for a page that links to [[vulnerable]]. The link to [[vulnerable]] will not appear anywhere in the rendered page's HTML source, although it is still present in the wikitext.
Fixed in r27981 and on Wikimedia.
