I agree there doesn't seem to be a good connection between work on version control and work on code search.

However, I don't think it makes sense to downplay git5. Anecdotally, basically everybody knew about it, and I'd constantly run into people using it (which is by itself noteworthy since nobody was exactly talking about version control all the time).

Git5 was at the time the most robust solution to chain commits, which was tedious bordering on impossible without some tool. Without definitive data, I wouldn't say users were less productive with git5: it definitely was a useful tool that people at least recommended for chain commits. I was definitely more productive with it.

There were a lot of footguns though, and I do think the hg wrapper that superseded it was way better.
