Tell that to every bank in Casablanca still running RHEL 6 with extended support. We patch certificates, not operating systems.
I use acme.sh because it runs on bash from 2010. No Python, no containers, no problem.
What about Traefik? Automatic LE, Docker labels, no shell scripts. I use it for homelab.
Traefik is fine if you are already containerized. The thread started with "heavy dependencies" as a concern. Traefik adds Go binary + Docker socket access + label magic. Different weight class.
For bare metal or simple VPS, acme.sh is the right answer. For Kubernetes, cert-manager. For Docker-only, maybe Traefik. Horses for courses.
