PR: https://github.com/analytics-zoo/vllm-xpu-kernels/pull/22
The PR author seems to have contributed to intel repos a lot and VLLM. He also shares his name (might be the same person?) with a person who is either a CTO somewhere at alibaba or the Director of Zhejiang Lab.
He has worked on Qwen3.8 before this.
The PR also implies the KV cache size for Qwen4-27B is not decreasing.
