Technically it isn't necessary to use the wrapped value when the wrapper function only takes a single parameter (because the virtual table could easily do the wrapping in this case). In the case of an insert, all wrappers only ever take a single parameter so it can be elided, but for updates some wrappers may require multiple parameters, so I opted for consistency and force all updates to use the wrapper methods, even when it only takes a single parameters.
