Is your feature request related to a problem? Please describe.

Currently, the cuda-bindings, cuda-core and cuda-python packages on PyPI publish only binary wheels. Source code is available from archives attached to releases, but it includes the whole repository and therefore does not integrate well with standard PEP 517 build process (read: you can't just pip install cuda-python-v12.9.0.tar.gz).

Describe the solution you'd like

While we can work around it, as downstream packagers we would find it much cleaner if you could provide source distributions for each project separately. If you don't want to upload them to PyPI, attaching to releases would also work.

Describe alternatives you've considered

No response

Additional context

I understand that there are currently some cross-package dependencies that require using the monorepo archive. However, I think they could be solved cleanly with help of some symlinks that turn into included subdirectories in sdist. If you agree, I can experiment a bit and prepare a pull request if I get something neat working.

Überprüfe die Packaging-Konfiguration für die Projekte cuda-bindings, cuda-core und cuda-python und vergleiche sie anschließend mit den Release-Archiven des gesamten Repositorys. Stelle sicher, dass jedes Projekt eine separate Source Distribution erzeugen kann, die mit einem standardmäßigen PEP-517-Build verwendbar ist, wobei die Abhängigkeiten zwischen den Paketen erhalten bleiben; abgeschlossen ist die Aufgabe, wenn die Distributionen an Releases angehängt oder auf PyPI veröffentlicht werden können.
