not only 'za', all non-existing codes (somebady copied interwiki from WP to Wikt => many unrecognized codes)

Okay `za` is an closed wiki but the API https://za.wiktionary.org/w/api.php still works like any other wiktionary. So to fix that the `Family` class in `pywikibot.families.wikitionary` should support `za` in `langs`. Now I'm not sure if there are obsolete codes where this doesn't apply. If that is not the case one fix would be to add the `obsolete` codes to `langs` or to not only check `langs` in `pywikibot.family.Family.hostname` but also `obsolete`. Otherwise `obsolete` need to differ between just //closed// wikis and //removed// wikis.

But your problem with `ht` is different (as explained above). Also why “not just”: That file has 2k+ lines and unline `pywikibot.site` or `pywikibot.page` which are also quite large, is the script one section. So to understand it you have know how it works.
