MW extension Polyglot (which doesnt appear to be in Phabricator) creates interlanguage links to the same wiki, and the 'code' doesnt exist in the interwikimap.
'it' is in the langlinks
http://botwiki.sno.cc/w/api.php?action=query&titles=Main_Page&prop=langlinks
'it' isnt in the interwikimap
http://botwiki.sno.cc/w/api.php?action=query&meta=siteinfo&siprop=interwikimap
This is currently causing two tests to fail on botwiki

UnknownSite: Language 'it' does not exist in family botwikiThe errors are due to the family file generator explicitly adding 'en' as a code, and no other valid codes.
Simple solutions include the generator not using any codes in the generated file, or manually add 'it' to the family class, pointing at the same URL, and fix whatever breaks.
However these simple solutions are a departure from our intention to use T74873: Family generator detection (tracking). But is this extension ( with ~75 wikis) worth special handling?
