The "what has no equivalent" section is the most valuable part of this guide — most migration content only sells the destination, while the honest diff is what actually de-risks the move. From my experience running multi-model workloads, the budget shape change (observed vs enforced) is the real operational difference: observed budgets teach you where money goes, enforced budgets protect you when a runaway agent finds an expensive loop at 3am. One thing I'd add for anyone migrating: keep the old observability stack read-only for a month before deleting anything — you'll want the old traces when the first cost anomaly shows up.
