dataservice replaces specific reverse family relationships with generic ones

[fiendish]

The dataservice replaces any participant2_to_participant1_relation value that you set if your participant1_to_participant2_relation is in its list of basic reverse relationships.

So if you submit e.g.

"participant1_to_participant2_relation": "Mother",
"participant2_to_participant1_relation": "Daughter"

The dataservice will always replace "Daughter" with "Child", because it says that "Child" is the reverse of "Mother". Is this forced replacement behavior intentional?

Should all family relationships be sexless? Should we be sending "Parent" instead of "Mother" and "Father" and rely on the participant sex field?
