Sadly that would not have helped in this case as the default-image-id config
setting was only ever implemented for Openstack and not EC2 AFAIK. The reason it
was done for Openstack was that there was, until now, no image metadata
available with which the correct image could be chosen. EC2 had the metadata
from the start.

Allowing any arbitrary image id to be used opens up the real possibility that
the wrong one will be specified and not match the tools used. So the convenience
is outweighed by the possibility of breaking Juju in weird and hard to debug
ways, and the support costs that would entail.

We are engaging with the folks who publish the simplestreams metadata to put
processes in place to ensure this doesn't happen again.
