E.g. if a patient record is added to a family outside of pedigree editor by not using internal APIs (e.g. via a data pull script for CLIN) a family member may end up being linked to a family, but not being mentioned in the pedigree even as an "unlinked" member, which introduces potential inconsistencies. Those can be fixed via a migration so it is not an immediate problem, but need ot discuss what takes priority: pedigree (if present), links via XWiki objects or "either or"
Relates to PT-3379, commit fe7461f44335
If (when) is extended to modify pedigree as well, and if only those APIs are used then there is no problem
