@NickThrew I don’t believe there is a list or final argument that decided it. There are certainly some cases where it does make sense, Sandstorm.io is the one that usually comes to mind for me.

Some have argued privacy reasons.
Here’s a link to one of the threads where people explain why they believe wildcards are needed: Please support wildcard certificates
