Forgetting the obvious security advantage for the moment, I've found this to actually be convenient that the lifetimes are rather short. I'm not disciplined when it comes to setting up my homelab projects, so in the past sometimes I'd just LE it and then worry about it when renewal failed. My family is the only consumer so who cares.
But then they set some shorter lifetime, and I was forced to set up automation and now I've gotten a way of doing it and it's pretty easy to do. So now I either `cloudflared` or make sure certbot is doing its thing.
Perhaps if they'd made that more inconvenient I would have started using Caddy or Traefik instead of my good old trusty nginx knowledge.
