You have to consider, though, which seems greater: the odds that we have a blue role that benefits from knowing what roles are out there (not who has them, just the role) or the odds that the wolves will benefit from knowing this (i.e. change their target). In the majority of games, even in crazy-mystery-unknown-majorly-blue-land, it's somewhat unlikely a role will directly benefit from knowing that another role exists, where as the wolves will certainly think twice if they know for sure that a guardian or similar role exists. If the information doesn't/can't benefit the wolves, then I agree, but that isn't always the case.
