Nearest neighbor techniques generally average over k nearest neighbors. This average makes a fine score. If k = 1, then score can only take on values 0 and 1, but that isn't a problem.
So I think that the interface makes sense. There isn't a link function, but it is traditional to take that as meaning that the link function is the identity function rather than that it doesn't exist. Or did I miss your point?
