It's not only run by the developer, it's also run by CRAN. The situation might happen where for a particular platform (e.g. Windows) that PkgB doesn't exist. It'd be nice to be able to avoid a situation where PkgA can't exist for that platform simply because PkgB - which isn't even necessarily required for PkgA to be used - doesn't exist for it.
