Part of this is on the core team IMO. For nova compute API microversion 
changes we also require a corresponding change in python-novaclient 
since the client is capped at the microversion it supports, and that is 
used when doing version negotiation with the server to determine the 
default version to use for the CLI (which is a different behavior from 
openstack CLI which just defaults to 2.1 for everything).

Anyway, the point is, we/I haven't considered a nova blueprint which 
adds a microversion as complete until the python-novaclient change is 
also merged.

osc-placement has sort of missed this because of an out of sight / out 
of mind kind of situation. With StoryBoard tracking placement features 
we could definitely track something like the server side work in 
placement itself as a task and the osc-placement related change as 
another task, so the overall story isn't complete until both parts are 
done (or the CLI task is invalidated for whatever reason - not all 
microversions require CLI changes).

Anyway, from a project management standpoint, it always helped me to 
know which nova blueprints weren't done yet because they still needed 
the CLI changes and then follow up on those.

I'm not familiar with vcrpy but a simple improvement if we're worried 
about the time it takes to spin up devstack for these functional jobs is 
simply trim down the list of enabled services in the devstack run. By 
default devstack is running with most everything [1] - for these tests 
we should be able to just enable keystone and placement. Granted I think 
devstack-gate modifies ENABLED_SERVICES a bit but you get the idea: we 
don't need glance/cinder/nova/neutron/etcd/tempest/horizon enabled in 
devstack for osc-placement functional tests.
