I really doubt they bother.

99% of people don't edit the commits by hand, they review and then tell Claude how to edit the commits (or leave a PR comment it reads), that's far easier to ingest than the tiny exhaust of manual edits.

LLM providers ask for RLHF feedback in terms of thumbs up/down in their Web UI. That's just one bit of information, given only at the user's whim. The hand-refined code is gold by comparison. They're already scraping all of GitHub. They have the technology and resources to semantic search. I would be shocked if they haven't at least tried.
