Is there some factor that militates against the development of this kind of cipher process?
The military and diplomats had no interest in making the enciphering process creative and fun. Like JKP, I believe that a family project is more likely than other possibilities, the secret was kept in a family and was never known to scholars who wrote books about the history of cryptography.
