But a 10-20 line shell script could, calling nova CLI commands.

I think the point here is that we see pushes like this to treat VMs as
pets and we've so far been able to successfully push back on these
(anti)feature requests, pointing out that this kind of thing generally
is antithetical to a utility cloud model and antithetical to the
horizontal scale-out architecture that cloud espouses (i.e. don't have a
single point of failure that requires this kind of setup).

/me waits for someone to use the word "enterprise".
