Just spoke to @ddstreet about the SYSTEMD-UDEV merges. We are discussing if we should keep the udev delta (from upstream) or not, considering that the issue will be already fixed by bcache-tools and udev change would only serve not to have backing devices at /dev/disk/by-uuid and /dev/disk/by-label (good for end user, but to add burden to ubuntu-devel).
