[Sylvain Bauza <sbauza@xxxxxxx>]

Thanks for your bug report. Unforutunatly, it doesn't really correspond
to a notion of either a regression or a technical issue, but rather a
missing feature.

We have a specific process for approving feature requests thru Launchpad
Blueprints and what we call 'specs', ie. formalized textual RFEs
describing the problem description and the proposal.

FWIW, what you're asking for is actually already approved for our Pike timeframe :
https://blueprints.launchpad.net/nova/+spec/service-hyper-uuid-in-api
http://specs.openstack.org/openstack/nova-specs/specs/pike/approved/service-hyper-uuid-in-api.html

I'd suggest you helping by at least reviewing the current series where
some patches have already merged
https://review.openstack.org/#/q/topic:bp/service-hyper-uuid-in-api,n,z
