I know that we advertised the usage of the io accessor functions for quite some time now. But I'm not so sure here anymore. One disadvantage of this usage could be speed penalty by the usage of too many unnecessary barriers (included via the accessor functions on some platforms).

Hot paths (or tiny bootstraps) can be optimized if needed, but why invite screwups for the majority of code?
