Good point, perhaps (age_in_years+1)×1M would be a better limit. Anyone wanting to import more than 1M commits could get a paid tier or beg support. At any rate, not that hard to implement is what I would expect

Git commit timestamps are 100% fudgeable. You could implement this based on GitHub repository age, but the assumptions would break for imported repos.

(Understanding we’re waaaay off in edge case territory here and this is all basically academic.)
