What is missed is ability to add references from Product. This limitation
is really annoying for projects with nested dependencies. For example I
have few libraries that depends on almost 10 drivers (each is separate
Product) so I have to define very long list of references in the project.
I understand it's kind of rare case. It seem to me kind of big change to
qbs.
Don't get me wrong, I don't complain about it just want to example it here
and maybe you guys implement it one day.

BTW, I applied this trick to remove "redundant" Depends in root Product:
Of course it's ugly trick but probably someone could find it useful for
existing projects...

import "RootProject.qbs" as RootProject

Project {

    references: ["libA.qbs", "libB.qbs", "libC.qbs"]

    RootProject {
    }
}

RootProject.qbs:

import qbs.FileInfo

Product {

    Depends { name: FileInfo.baseName(project.references[0]);
condition: !!project.references[0]  && autoDepends }

    Depends { name: FileInfo.baseName(project.references[1]);
condition: !!project.references[1]  && autoDepends }

    Depends { name: FileInfo.baseName(project.references[2]);
condition: !!project.references[2]  && autoDepends }

    // Add reasonable amount of possible dependencies.

}
