I'm responding to a Nix user making this about how Nix does timing. I'm relating it to the common thread of cargo cult'ing shared between systemd and users of Nix as desktop operating systems. They both increase the amount of config files necessary to accomplish what should be almost config-less tasks and spread those config files out across many places instead of a single config store that is for the entire OS.
It's bad policy for desktops even if it's good for you in work environments and so you use it anyway. Normalizing that is bad. I said it like a jerk though. Sorry.
