I think we need to specify the concept of "feature" for plugins and the 
notion of plugin dependency of "features".
Try to explain :

    * Plugin A implement the Feature 1
    * Plugin B also implement the feature 1

    * Plugin C depends on the feature 1

For instance, Plugin C is the dispatcher and Plugins A and B two 
implementations of the core.theme
So what ?

Projects can select their implementations :
    If a project specifies project.required.plugins=C, A, it's OK,
    If a project specifies project.required.plugins=C, B, it's OK too - 
but with a different behaviour or rendering,
