I think Barry is only suggesting we save the state integer.

That's okay, but if we add that, it should only be a warning for a while. Fortran (77) can't enforce this constness and none of the examples use VecGetArrayReadF90 yet. Plenty of users may have internal interfaces that are reused between const and non-const usage, so requiring VecGetArrayRead could cascade into lots of their internal interfaces.
