The only thing keeping me from switching is the removal of "distributed LetsEncrypt" in 2.0. I get that it's a non-issue for k8s setups with cert-manager, but people aren't always using k8s and it's still a feature in the enterprise edition.
Could you elaborate what you mean? While it'd be ideal to store certs in vault, I'm having it run fine in orchestrated containerization with the cert storage on a distributed filesystem.
