Problem is that those companions are meant to be the main protagonists and this is another way to add replayability as you playing them you have to deal with 'your big issue' as well as the tadpole... an approach that I don't like at all, as the stories get spoilered once you had them as companions in one playthrough and their additional as protagonists consumes a lot or resources, not to mention that they all feel hopelessly over the top.
