This shouldn't be surprising. Astral has wanted to create lock-in with uv for years and obviously they'll want to bring everyone into their "ecosystem" as much as possible. Stand by for more divergences from main python or use of their "market" capture for leverage over it.
Main python should move faster on standardizing fixes to its abysmal package distribution scheme, then. Nobody is trying to replace cargo.
Lock in on uv isn't a terrible thing if you consider the abysmal state of Python tooling
It's not something I really relate to, having working on a fairly large project with significant dependencies that is used as both a library and an application. I see uv often used just to try to paper over bad dependency and compatibility management, which ends up being self-reinforcing. I guess if it's being used strictly for final deployment, sure, but that doesn't (shouldn't) remove the need to pay attention. It's hard for me to see it as anything but an attempt to eventually make the state of Python tooling be "everything breaks, unless you use uv by Astral™"
To what end? Do they make money off of it somehow?
