Hi! I believe this is an issue with ifupdown, rather than cloud-init. As such, I've added an ifupdown task and marked cloud-init's task as Invalid. If it's determined that we won't fix this in ifupdown, then please move the cloud-init task back to New and we can consider working around this in cloud-init.
In the meantime, you'll have to modify /etc/network/interfaces yourself to perform the sourcing. Thanks!
