This is useful so that during shutdown scope units are always terminated before the mounts necessary for the home directory. (Ideally we'd also add a similar dependency from the user@.service instance to the home directory, but this isn't as easy as that service is defined statically and not dynamically, and hence not easy to modify dynamically, in particular when it comes to deps)
