This is a case where exceeding the spec would be a very good thing.
And there has been lots of research on how to make more complex views
updatable; see Date's _Introduction to Database Systems, 7th Edition_

That said, one step at a time is always good, and even having just the
very simplest views updatable would be a very nice thing.
