Does a broad consensus want the category to be narrowed to direct-line only? If there is drive to narrow to direct-line ancestors, should that not be made in a new project such as, for example, "US President Direct Line"? It seems that many people might want to know about collateral relationships in a large tree project like Wikitree, in comparison with personal trees such as are presented elsewhere. Why not have both direct and collateral relationship projects? Collateral relationships could have a limit to how many marriages can be involved. Note that half-sister/brothers can have the same parent, either mother or father, meaning still genetically related. And if the limitation on the number of marriages, then 3 categories to include direct, collateral within 'three degrees' for example, and collateral beyond 'three degrees', etc. That way, people are not excluded, and yet the category has some significance. Or, are such divisions necessary at all?
Are we ready to tell people that their relationship to a president is of no significance if it is not direct-line?
What does seem significant, however, is the control of individual profiles for individual people by other people who are relatively distant in relationship, and so might have limited understanding of the family history..
