> So, you'd think that something that pretends to be “Artificial Intelligence” would use the most efficient way of using our data for training purposes, right? Clone the repos, walk every commit. Done.

If repos like this were 10%+ of what they crawled, having a special case for clone-able repos would be smart, but if you're crawling everything, you're not going to do an efficiency tweak for each special case that has a more parse-able option.
