Certificates from Let's Encrypt can be issued only after a domain validation. How much chances you have for a newly added domain to pass a domain validation?
Pretty much because normally you register them with the registrar direct after putting them on the server or right before.
And autossl on cPanel runs on a nightly cronjob which checks if a domains has a certificat and if not, requests it automatically.

Nice feature. Makes life easier for admins and users. Since every thing nowadays really needs SSL this works nicely.
I agree with what Richard said. I know that cPanel automatically does this and it is one feature that really sets them above Directadmin at this moment in time. Most people use the Chrome browser these days and without an automatic SSL certificate for each website, it automatically looks suspicious and would scare most casual users away. I want to set up a new hosting service like Wix or Weebly on my own servers but can't do so without the autoSSL feature like cPanel has. I love Directadmin and have used them as my servers for more than a decade but now that SSL is standard on all websites it's time for Directadmin to also make this a standard feature. I can set up what I want on cPanel to get this done but I sure don't want to have to move to cPanel to do it. Most casual users don't care about the benefits of a more expensive paid certificate - they just want one that works without having to know anything techie about how to create it.
It would be nice if there would be an autoSSL feature (maybe switchable for packages) because SSL is almost always needed these days. Auto SSL does like run a nightly cronjob and see which new domains are created. For these domains an SSL certificate is
