I looked up RFC8499 and found that although the definitions of Master and Slave appear (only) as references to Primary and Secondary, the old terms still are used extensively in the bodies of the definitions. (Not to mention that it would be rather confusing to have "Primary master" defined as a reference to "Primary primary".)
