I think that with the recent-ish kernel changes to make /dev/urandom non-blocking, rngd should not be installed by default. As for crond and atd, I think we can keep them installed by default, but inactive. I.e. make them socket activated or path activated, so that they are only started if people install actual crontabs or run at. We would also need to convert any packaged cronfiles into systemd timers. But it seems that this is already mostly done. On my machine, /etc/cron.weekly/98-zfs-fuse-scrub is the only real crontab entry. Those are not big programs, but each thing that is running on a machine has some small impact... I see the appeal of keeping them functional by default: there are countless manual on the web, and even if people use them nowadays much less than in the past, it'd still be nice to make this "just work" for people who follow them. In the past, I saw pcp as a fairly big offender. I'm not sure if it still installed by default.
