Issue

After migrating to rattler-build, it appears that CI now takes forever to build Linux builds. It seem to be because rattler-build now only has to generate the noarch cuda-python once, and then proceeds to build cuda-bindings for py310, py311, py312, and py313 (and py313t). It is technically more efficient in terms of what is built, but parallelism is lost. It’d be great to get rattler-build or conda-smithy to build Linux builds the same way conda-build did, even if it means cuda-python is built 5 times (one for each Python variant) than once.
