As I understand it, newly issued certificates are considered renewals for rate limiting purposes if they contain the [exact same set of FQDNs](https://community.letsencrypt.org/t/rate-limits-for-lets-encrypt/6769) (domains and subdomains) as an existing certificate - it should not matter whether you use the renew command or not.
