We support this now by setting an impossible marker, e.g., override-dependencies = ["package; sys_platform = "never"] (https://docs.astral.sh/uv/reference/settings/#override-dependencies). We should add a dedicated option, e.g., excluded-dependencies = ["package"]. Unlike --no-install-package, this omits the whole dependency tree. We should add a dedicated option, as this is fairly bespoke.
