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.
