I hadn't considered capping the python APIs in novaclient like this, but 
it was something I was wondering about. The image and baremetal CLI/APIs 
in novaclient have already been deprecated, but we don't cap those in 
the API, nor do we try and make it a soft landing for the CLIs. The only 
reason the network stuff gets a temporary pass on the CLI side is for 
nova-network users.

That's also because the CLI defaults to 2.latest, the API doesn't. So 
for the API you have to opt into use newer versions, right? If that's 
the case, then you would need to consciously request 2.36 on those proxy 
APIs for them to fail, which I'm hoping people aren't going to be doing, 
or at least they should be reading the REST API version history first to 
see what they are opting into.
