It should be possible to somehow check which languages are supported as they are and which should be hard redirected to some other language. This is not about fallback languages, but on which languages we support.

We should publish Utils::getLanguageCodes() somehow, which language we use as replacement when a language specific string is missing, and also which one we can convert through transliteration. Similarly we should include this information in wbgetentities if we use it somehow. Perhaps it is simplest to add a section about this if the requester asks for this information.

For example can strings in some language A be a replacement for some other language B as long as an alternate string is not defined in language A.

Also, if a language variant A is only different in transliteration from language variant B, then strings in language B can be replaced by transliterating (converting) strings from A.
