Launch scripts in ~/config/data/user_launch don't work

[humdinger]

This is hrev50627.

I have a package that installs this launch script in $data/user_launch:

target desktop {
	service x-vnd.Clipdinger {
		if setting ~/config/settings/Clipdinger/Clipdinger_settings autostart
		no_safemode
		legacy
	}
}

When the package is installed in the system hierarchy, Clipdinger is started on boot. If it's installed in the home hierarchy, it's not. As the launch_daemon is supposed to launch via app signature, it shouldn't matter in which hierarchy the binary ended up in, right? Am I missing something?

After installing, make sure to run the app and check the auto-start option.
