What advantage do squares have over rectangles?
As AJ Slater states, polyfidelity is a subset of polyamory, rather than an alternative to it.
This highlights at least one the main advantages: by being a specific subset of a larger/sweeping/more generalized practice, it may be easier to reach agreements over definitions and boundaries within a relationship.
Polyamory in the generalized sense, by contrast, may have a different meaning for every member or even bystander to a relationship, which in turn may signify the need for increased frequency of checkins/communication to ensure that everyone's "on the same page", at least until some rebalancing and renegotiation has occurred to the point in which roles and responsibilities are universally understood, rather than assumed.
