OK, discussing with GNU coreutils maintainers looks rather futile. How about we provide uptime via update-alternatives from different sources (busybox, procps, coreutils)? I can in fact uninstall coreutils-systemd, but I cannot install busybox-coreutils because of... Problem: the to be installed busybox-coreutils-1.36.1-30.1.noarch conflicts with 'coreutils' provided by the installed coreutils-9.4-1.2.x86_64 So maybe we can make this co-installable? Or create a busybox-uptime and a coreutils-uptime which are conflicting over only the uptime job?
