What we have too few rather than too many questions, what actual problem would yet another split solve? Java questions do not prevent anyone from talking about Excel or Python or Stackoverflow. And we have a lot of great answers to visa/residence permit questions, it's not like they create special difficulties as your question would seem to imply.
It's true that we could do with more questions about other aspects of life in another country but I have not seen many good questions or answers about that. I don't think getting rid of the bits that actually work on this site is going to make this any better.
