Well, this would not be leaving the profile alone. It would be de-linking the profile from any parent, spouse or child that one does not have some reason to retain a link to, and then presenting the material in the biography.
One of the things that many WikiTreers want, including, especially including those who are less skilled, is a connected family tree. By leaving connections that are quite dubious, one has become complicit in providing these WikiTree users something which is most likely to be false. That is not fair to them.
