I think the idea is enticing, but it comes with some challenges: 1. Rust is strongly typed so when extracting values we would likely need a `Scalar` type enum or multiple different `value_bool`, `value_u64` type functions 2. Such access would likely be much slower (though possible more convenient) as it would dispatch based on type for each row (whereas the downcast_as pattern does that dispatch once per array)
