Yes, in general, I've assumed that changing the model requires changing
the view columns. But I guess that's not necessarily the case if the
model has exactly the same column types.

A patch would be welcome to fix this.

Probably, yes. They are only quick convenience functions anyway. In most
real-world situations you need more complex logic for control of
validation of input and for formatting of displayed data.
