to my understanding, it's for those who can imagine (and predict time) how to write simple additional httprequest to external URI and create simple `route` in their NodeJS app [for getting callbacks], but who's not confident on wtf is `man systemd.timer` (smells like all dead sysadmins' zombie magic) which `service unit` it should trigger and what actually to run under that service unit. How to deploy all that after all. Indie/solo devs, if that express state of things better, who are assured their product will be never run in internal/isolated networking, for example or never need to stop some specific cron but not all of them during migration, blah blah blah.
