I don't see how it works in practice, because there is no way to police it.
I understand the desire to have regionalized resources, and how that can
make many deployments simpler. What I don't see is how an RIR is in a
position to police where a resource gets deployed. The justification
documents can show in-region use, but the separation between assignment and
operations allows the recipient to move the resources anywhere at any time.
If you can figure out some language that allows staff to make consistent
judgments about regionalized deployments, I can live with that, but I am
skeptical. If someone came in with deployments A,B,C,D,&E, stating that A
has resources from RIR-A meeting policy V, B has resources from RIR-B
meeting policy W ... now requesting resources for E from RIR-E meeting
policy Z, (and there was a background check process in place to verify that
what is claimed is what was used at the other RIRs) that would be easy
enough for staff to deal with and create a document trail about why an
action was taken. Where it breaks down is that the pace of change is faster
than processes can deal with, so in real deployment it is never as clean as
the documented justification. I am not suggesting people are intentionally
bypassing policy, just that the best intentions are rarely the outcome.
Once you get into the messy real-world, it is very difficult to weed out
those who are intentionally bypassing policy from those that are simply
victims of process delays. Developing a policy that can't be enforced may
put a feel-good feather in someone's cap, but it does nothing but create an
impossible situation for staff. At the end of the day it would appear to be
cleaner to have every RIR evaluate global deployed resources against local
policy every time. Once resources are assigned you can't reasonably police
where they are used, so don't even pretend to try.
