For rebasing `--reapply-cherry-picks` will avoid the annoying fetching you saw. `git backfill` is great for fetching the history of a file before running `git blame` on that file. I'm not sure how much it will help with detecting upstream cherry-picks.
Oh, interesting! Tbh I don't fully understand what "--reapply-cherry-picks" really does, because the docs are very concise and hand-wavy, and _why_ it doesn't need the fetches? Why it is not the default?
