> Sometimes it is possible to fix a violation by exchanging replicas between
> two nodes. But the current suggestion API cannot do that in cases where each
> individual move operation increases violations. We should introduce a
> two-step swap operation during policy computations (no SWAP API is planned)
> which allows us to achieve this goal even if intermediate operations violate
> policy rules.
