From workload-variant-autoscaler to llm-d-autoscaling: retiring a custom engine for KEDA + EPP
llm-d-workload-variant-autoscaler (WVA) is being renamed to llm-d-autoscaling. At the same time, the part of WVA that made it an "autoscaler" — the analyzers and cost-aware optimizer that turned Prometheus metrics into a wva_desired_replicas signal — is deprecated and will be removed from the repository. Instead, we're pointing KEDA directly at metrics that EPP now produces on its own. Quota-constrained environments get the same treatment: instead of WVA's own GPU quota limiter, we're pointing operators at Kueue, Slurm, and LSF — tools already built and trusted for that job.
That scaling-decision pipeline — the part of WVA that reads metrics and computes a replica count, as opposed to the CRDs and controller code around it — ships as-is in release v0.9 and won't get further updates.
