For graphical applications we are using Flatpaks to get this separation of OS upgrade and application upgrade, *but* we're planning to have applications be single stream - so applications just roll forward with upstream stable releases. So the total complexity stays low.

Even creating a decent command line experience around it seems very difficult, since if you allow independent module maintenance, two modules can start conflicting at any time (even without a branch switch!). "Updated versions of reviewboard and sagemath have different versions of python2-<something>, do you want to" A) Remove reviewboard B) Remove sagemath C) Use the version of python2-<something> from reviewboard and hope for the best D) Use the version of python2-<something> from sagemath and hope for the best E) Find a nearby brick wall to bang your head against On the other hand, if you don't allow independent module maintenance and enforce compatible versions across the entire set of modules included in the modular compose, you've lost some of the point of modularity... still, that's better, in my opinion than presenting the user with lose-lose options.
