Cloud-init uses default generated network config to try and configure a link for DHCP. This overwrites the LINKDELAY setting, which is required in some cases to bring up the link.

This seems like quite a drastic thing to always do. Network bootstrapping is a big part of cloud-init. Would it not also break network configuration provided via config-drive?

This prevents the configuration of a udev rule by cloud init and the addition of the MAC address to the ifcfg script for the active interface. DNS still appears to be configured, but is missing the 'configured by Cloud init header'. None of these issues appear to prevent the image booting, running cloud-init and enabling the user to log in on a test node connected to a single network.
