How can we force this to be just _router: EmberRouter;?

What is this checking? What is properties here?

properties is Object.assign({}, injections, createProps) basically. So it's possible that the implicit injection has been overridden by an explicit value (an argument in a classic component for instance)

What this change intended? Based on the code changes, it seems so?

Yes, after thinking about it some more my conclusion was that we can't really assert about getters, specifically because when a user defines a getter, they also must define a setter. Otherwise, the implicit injection will do nothing (or error, if JS strict mode is enabled). With that in mind, its possible that the user could define a setter that swallows the implicit injection, handling the deprecated behavior essentially.
Happy to discuss further if that doesn't make sense
