Certbot (and other acme clients such as acme.sh) are practically set and forget. I’ve never once had to touch those configs again once they were made ~4 years ago.
But I would agree here, even when I had the problems with LE (botched cron config) it only required me to 'administer' it 4 times a year. And when I fixed cron config I don't need to do even that.
