Neat, I've used lego (https://github.com/go-acme/lego) but will certainly have to give uacme a look, love me a simple ACME client.

acme.sh was too garish for my liking, even as a guy that likes his fair share of shell scripts. And obviously certbot is a non-starter because of snap.

Certbot has earned my ire on just about every occasion I've had to interact with it. It is a terrible program and I can't wait to finish replacing it everywhere.

The new setup is using uAcme and nsupdate to do DNS-01 challenges. No more fiddling with any issues in the web server config for a particular virtual host, like some errant rewrite rule that prevents access to .well-known/.
