I like this approach. It sounds, by and large, like what I had to do
to get the end-to-end tests for create_node() working. The region had
to query the cluster for supported OSes and architectures before it
could build the form through which we created the node. An awful lot
of mockery went into making sure that everything worked smoothly.
