No, investigating scummy power roles is also an excellent use. In order to catch a night kill he has to hit the wolf making the kill, whereas here he has a disputed power role that may well be made up.
One problem with the whole busting/confirming Mattimeo approach is that he may well have a cloaking ability which either does what he says it does (but he is scum) or does something else (and he is scum). The only way to catch Mattimeo would be to catch him lying, and it seems that chance has been wasted
