+rationale: |
+    The terms grandfathered and grandfather clause are sometimes used to indicate the following:
+
+    - To allow compliance exemption from new or updated policies / terms.
+    - To allow a legacy software system to exist outside of current best practices.
+
+    These terms have roots in 19th century racially motivated voter disenfranchisement efforts.
