Unless I'm mistaken, this is because dhcpcd forks to the background and dynamically switches between IPv4LL and DHCP/RA addresses as needed. I'm not sure whether changing this behavior is remotely desirable. However, I do agree that if this makes ifupdown presume that an external IP has succesfully been acquired and the boot process continue to steps that launch network-dependant services, it is problematic.
