That is exactly why I give a lot of credit to a "lost tradition" way of thinking. "Auteurs" were just extremely rare. And if we assume a lost tradition, we may find partial parallels in other traditions.
What you say about strict rules and materials being scarce is also something I always keep in mind when assessing a Voynich theory. Too many people assume medieval scribes had large stacks of vellum lying around to mess around with.
