I don't think it's a bad idea to provide a shortcut for human users. The
important point is just that internally it's not the main interface, but

Not sure how much easier the review would become, but the obvious split
that works almost always is to do a read-only driver in patch 1, and
then add write and create support in patches 2 and 3.
