  My 2 cents on this, that's normal implementation dependant situation in library, so about me it has 2 approaches:
  
  1. Always adds new required implementation in new class, then port existing users on it, leave orphaned classes to be removed
  2. To not break API/ABI it can be added a constructor by dependency injection the new implementation. It's a bit tricky, KTextEditor uses it, but it's not that bad.
  
  Returning implementation to the client can be good if it's not expected any other client(s) to use it, if not that's not good.
