This is actually a very good comment that helps newbies decide whether they should create/need a "universal" app or not for SPAs. To add to this, there's also the claim about code reuse.
There are other initiatives in the ember-verse for solving the 'universal app' issue.
Specifically, ember-engines provides a way to separate code into logical apps, but having them appear to be a single app. It's currently 'experimental', but in very active development.
For us, it provides the best-of-both worlds... a single interface to the customer, without having to load up all of the code, services, etc that are used in every corner of the app.
