Sure.

When we say "dependency", what we really mean is the dependency in INF file, 
not "dependency" in DSC file.

>From package release perspective, only INF is the interface to other package. 
The DSC is only the package internal stuff, you can create multiple DSCs or 
add/remove DSC freely.

Having "dependency" in DSC does not matter.
Having dependency in INF is something we should care about.

Thank you
