I would prefer it as another dialogue option instead. It seems to me that using the tadpole too much causes some currently unknown negative effects. Don't remember what exactly happened but there was something mentioned about losing something you will never get back.
I noticed this as well. Seems to not be implemented yet. I also thought there was a serious time restraint on getting the tadpole out so never rested, or rested as little as possible. Apparently there is currently absolutely no urgency to have the tadpole removed.
