> Also, what's with using unofficial Python builds by default? Even on platforms where official builds exist (macOS/Windows)? I get that these standalone builds solve certain problems (like bootstrapping), but it feels like a risky shortcut. If those unofficial builds go unsupported or change directions, where does that leave "uv"? Why not at least give users the option to rely on official binaries?

The official macOS binaries wouldn't work for uv because they're not portable. They're also taking ownership over the indygreg project which is a great thing for everyone since portable pythons are useful in a lot of contexts. I'm sure they'll start sending some of the portability changes upstream too once they get there.

I don't see how this is criticism.
