Hm, doesn't Caddy support wildcards without DNS auth? It seems that they work around this by generating a few random subdomains and verify those.

From the Caddy release announcement that supports wildcards[1]:

"This release introduces support for wildcard certificates, a new offering from Let's Encrypt. Getting a wildcard certificate requires enabling the DNS challenge. Fortunately, that is extremely simple with Caddy, and it works with over 20 different providers!"

Caddy requires configuring their DNS provider as well[1]. LetsEncrypt (and ACMEv2) only allow you to get a wildcard if you use the dns-01 challenge.
