This is my suspicion, all though I have no evidence, just anecdotes. I make a handful of commits a day. I write code, review it, test it, commit, and then push.
We have some marketing folks that have gotten into vibe coding stuff for their personal use. First let me say: good for them and I'm glad they're experimenting with new ideas and tools. The side effect of that is that looking at their repos, they're having Claude go whole hog and make upwards of hundreds of commits a day, all with things that they haven't taken a look at.
I don't think I can say this is wrong of them, because their tools encourage that and they shouldn't have to consider their impact on an enterprise service, but I wonder if this trend is similar in other places.
