I can only cite my experiences doing devops on AWS for the past 5
years, but I personally avoid relying on cloud-init on EC2 and try to
catch when other developers use it to do something because there's
always a better way.  That better way is almost always to add a
one-shot systemd service (these are not Guix System servers) to the VM
image that starts on boot.  What are some situations in which
cloud-init is unavoidable?  I wouldn't think cloud-init would need to
start sshd since the init system would automatically do that.

None of this is to say that I wouldn't be in favor of having
cloud-init support.  I'm just trying to understand if it's a necessity
in a certain context or if it would be for the purpose of providing a
familiar tool to help people who are used to using it with other
distros.
