They died because everyone knows that Python is infact very very slow. And that’s just totally fine for a vast number of glue operations.
It’s amusing you call Git fast. It’s notoriously problematic for large repos such that virtually every BigTech company has made a custom rewrite at some point or another!
Now that is interesting too, because git is very fast for all I have ever done. It may not scale to Google monorepo size, it would ve the wrong tool for that. But if you are talking Linux kernel source scale, it asolutely, is fast enough even for that.
For everything I've ever done, git was practically instant (except network IO of course). It's one of the fastest and most reliable tools I know. If it isn't fast for you, chances are you are on a slow Windows filesysrem additionally impeded by a Virus scanner.
The fact that Git has an extremely strong preference for storing full and complete history on every machine is a major annoyance! “Except for network IO” is not a valid excuse imho. Cloning the Linux kernel should take only a few seconds. It does not. This is slow and bad.
The mere fact that Git is unable to handle large binary files makes it an unusable tool for literally every project I have ever worked on in my entire career.
git clone --bare --depth=1 https://github.com/torvalds/linux
Takes 21 seconds on my work laptop, indeed a corporate Windows laptop with antivirus installed. Majority of that time is simply network I/O. The cloned repository is 276 MB large.
Actually checking the kernel out takes 90 seconds. This amounts to creating 99195 individual files, totaling 2 GB of data. Expect this to be ~10 times faster on a Linux file system.
So what's your problem?
Git-lfs exists for a while now. Does that fix your issue? Or do you mean that it doesn’t support binary diffs?

Git handles large text files and large directories fairly poorly too.
