Grafts in Guix support this use case: you know you're providing an ABI-compatible package replacement and don't want to rebuild everything that depends on it: https://guix.gnu.org/en/blog/2020/grafts-continued/ https://guix.gnu.org/en/blog/2020/grafts-continued/ We use that for security updates, but also in other situations where we know we can take advantage of it such as the new `--tune` package transformation option, which tunes a package for a specific CPU: https://hpc.guix.info/blog/2022/01/tuning-packages-for-a-cpu-micro-architecture/ https://hpc.guix.info/blog/2022/01/tuning-packages-for-a-cpu... Similarly, as a user, you can "graft" a replacement straight from the command line using `--with-graft`: https://guix.gnu.org/manual/devel/en/html_node/Package-Transformation-Options.html https://guix.gnu.org/manual/devel/en/html_node/Package-Trans...
