Is there any association that's not bi-directional?

As in a previous reply:

It would be helpful if the Association showed both parties of an Association and if there is any reciprocal/symmetrical association. Right now, it is ambiguous whether the Association describes the Selected person’s relationship with the Active person or the other way around. Having both shown would disambiguate this AND give the opportunity to set up a reciprocal relationship without popping yet another dialog.

Note that my example uses genderless “Godparent”/“Godchild”. The default being “Godfather” when associated person is female (or other) is awkward.

Godparent was added as a standard Role. It is intended for use with shared Baptism or Christening even.
See the “How do we harmonize custom data with a new standard feature?” discussion.
