That's why I'm only half-minded. But yes, I am saying that. The more I think
about it, having a tailored image with cloud-init might be the way to go --
then we can measure and see how much it is used in comparison.

Alternately, here's a crazy idea: the min-metadata service could detect if
userdata is in a syntax it doesn't understand and fire off a helper script.
That helper script could then install and exec cloud-init.
