I was curious, so I booted up a buster instance on ec2 to track this down.
cloud-init does manage /etc/hosts, due to this:
https://salsa.debian.org/cloud-team/debian-cloud-images/-/blob/master/config_space/files/etc/cloud/cloud.cfg.d/01_debian_cloud.cfg/EC2#L2

So I think zigo's approach seems reasonable.  Bastian - can you explain or
point to the discussion on why this would be controversial?

Thanks,
Ross
