Each routing protocol has its own metric semantic and therefore is the protocol itself the only component able to compare two metrics to check similarity similarity.
This new API allows each routing protocol to implement its own logic and make the external code protocol agnostic.

You might want to use abs(metric - new_metric) here, otherwise is_similar(a, b) output might differ from is_similar(b, a).
