Let's Encrypt certs are valid for 90 days.

There are 2 reasons: 1. To limit damage from key compromise and mis-issuance 2. To encourage automation.

What is the issue with running the certbot on your server? It's not like you have to run it manually.

P.S. Wildcard certs are available for almost a year now: https://community.letsencrypt.org/t/acme-v2-production-envir...
