Gentoo developer Michał Górny argues against using uv-build as a Python build backend, citing its large Rust dependency footprint, excessive rebuild times due to frequent releases, and portability issues across platforms. He contrasts it with lightweight pure-Python alternatives like flit-core, noting that uv-build's benefits don't outweigh these drawbacks for pure Python packages.
Background
uv-build is a Python PEP 517 build backend provided by Astral's uv project, gaining traction as a faster alternative to traditional backends. The controversy centers on its Rust-based implementation making it impractical for source-based Linux distributions like Gentoo.
