DNF doesn't do that and never will.

I would be glad if the packagers/users come with undefined scenarios and file BZ on DNF with: * "[weak deps]" summary prefix * post link to custom COPR, so we can reproduce it easily * write "expected" result then RPM team decides how DNF should act, change it accordingly and document this case. FYI I have added to DNF github wiki page [1] how to report different kinds of bugs.
