alt Hacker NewsI think that’s actually a different problem: packages that use uv-build for their backend should use a semver range, which enables the kind of “pick a version and use it” strategy I mentioned before.
(This is the default when you initialize a project with uv, so I think someone would need to go out of their way to configure their build backend to request a specific patch version of uv-build.)

This wouldn't necessarily solve Gentoo's problem. The only way to be sure to solve Gentoo's problem would be for every Python project that uses uv-build to specify one particular version. Then Gentoo could be sure that once that release of that project was built once, it would never change.
In other words, for a distro like Gentoo, the build backend is a dependency, and if it changes, that triggers a change in the build, even if the build backend change would not actually change the final wheel that got built.
