It does not specifically need to be a fault or retirement, it may be as simple as repurposing to a different operational domain. From an OpenStack perspective this should not require any special handling from "retirement", it's just to know that there may be time constraints implied in a policy change that could potentially be ignored in a "retirement scenario".

You raise a really good point and we've had some past discussions from
a standpoint of leasing hardware between clusters. One was ultimately
to allow for a federated model where ironic could talk to ironic,
however... that wasn't a very well received idea because it would mean
ironic could become aware of other ironics... And soon ironic takes
over the rest of the world.
