As @martin_kirch pointed out, the #uv project is working on adding its own #PEP517 builder.
This is just terrifying! Please consider joining me in raising concerns about it.
uv is a great tool! I do love it as a #Python package manager. But it is not very portable (even less portable than #RustLang in general, e.g. I'm still working on getting it fixed for PPC), and it is very heavy. And its popularity means that a lot of pure Python packages will now have a dependency on this non-pure, non-portable, heavy build backend that they don't really need.
This is going to be a true nightmare for downstreams. Just imagine me filing bugs, repeatedly asking people "please don't use this build backend, we can't build your package anymore because uv is non-portable!" And this will surely result in a lot of frustration, negativity, knee-jerk reactions and downstream patching just to keep things installable.
