Exciting! Looking forward to it. I end up needing xcaddy for a few other modules so it's not that big of a deal, but I always feel better using first-party functionality over relying on third-party modules.
There's even a great docker with caddy and the cloudflare DNS-01 module built in which was just what I needed. That saved me having to deal with xcaddy (it was ok, but compiling was slow)
