If I take Apple's goodwill (which in this specific case to me is plausible, but whatever ...) the issue with alternate notification channels is that it's quite tough to attribute for users if there are 10 push daemons doing it their way. But the bad press about bad battery life time hits Apple. Especially if Apple allows others to move it from application layer to system layer (by providing a Kernel interface?) which is required for being really energy efficient.
