Disclaimer: I am one of the authors of the project.
I do wish that NGINX made LetsEncrypt as easy as to use as Caddy does. We are all big fans of LetsEncrypt and are quite happy to see NGINX donating to the project.
In this project (MARA), LetsEncrypt support is integrated via [Cert Manager](https://cert-manager.io/) for Kubernetes. This is nice because it supports certs from a variety of issuers like AWS, Google, Vault, Cloudflare, etc in addition to Let's Encrypt.
