Note on the exclusion set. vLLM's CODEOWNERS names 56 people, so "excluding maintainers" removes essentially the entire top of both lists — the including-maintainers contributor top-10 is 100% code owners. This is not apples-to-apples with the PyTorch report, where only 5 hand-picked core maintainers were excluded. Narrow the set to project leads (e.g. WoosukKwon, simon-mo, zhuohan123, youkaichao, robertgshaw2-redhat) if you want a comparable cut.
