Last time I checked, you need an initramfs to make that work.
You are absolutely right; the kernel only supports "PARTUUID=" out-of-the-box (/usr/src/linux/init/do_mounts.c:218), the "LABEL=" ids are implemented by the initramfs, dracut in my case (/usr/lib/dracut/modules.d/98dracut-systemd/rootfs-generator.sh:87). The "LABEL=" id gets translated to the corresponding /dev/disks/by-label link, so those are the ones that should be used all the time. Thanks for the clarification.
