Thats certainly my understanding and one of the reasons I dislike it :).

Being able to update it when the guest is restarted would be an
improvement IMO - but note that the EC2 metadata service is largely
static too; thats something I'd like to see us change (e.g. making ssh
keys more dynamic)... but thats a different story.

I suggest putting a blueprint together, as the exact places where it's
safe to update an instance-mounted image will need careful
identification.
